So I am reading an article on ZDNet.com and on top of the article I come across a set of icons. See the image below. A couple of them are obvious. I can print the article or email it to someone. A more interesting one is the little rectangle with up/down thumbs along with a few numbers. This enables me to rate the article by giving it a thumbs up or down, which provides a metric on its worthiness. As you can see, this particular article has 71 votes with an overall score of +45.

The curious item in the set is the “share” icon which expands to many other items as shown above. A few are familiar household names such as Google, Yahoo! and Facebook. While others such as Digg (www.digg.com), Delicious (www.delicious.com), StumbleUpon (www.stumbleupon.com), Reddit (www.reddit.com) and Technorati (www.technorati.com) are lesser known.

Most news and media sites nowadays provide a few of these next to any article or news item. For example, The Wall Street Journal (www.wsj.com) lists Mixx (www.mixx.com) and NewsVine (www.newsvine.com) among others. While AIIM (www.aiim.org) includes Xanga (www.xanga.com), FriendFeed (www.friendfeed.com) and Propeller (www.propeller.com) in addition to the more common ones. So what exactly are these? What are they good for? And how do we use them?

A Bit of History and Lessons Learned

Back in 2005 a friend one day said that she had an idea for a new business: a web site for storing bookmarks on the internet. I smiled and said that it would be useful but I didn’t think that it was enough to sustain a business. I argued that a company like Yahoo! could easily add that feature. Secondly, it was technically very easy, so anyone could do it. It would be hard to build sustainable competitive advantage around it. More importantly I didn’t see how anyone could make money with it. Well, I had certain valid points. For one, Yahoo! did its own bookmarking site called Yahoo! Buzz. But I was wrong overall.

After the painful lessons of 2000-2001 in the San Francisco Bay Area, I was of the belief that a simple idea with no revenue potential cannot be a successful business, regardless of the hype and a catchy domain name. But the reality is that the web doesn’t follow the traditional business model. And the advent of the social web in the early to mid 2000s has once again redefined the norm, scale and the possibilities of what an internet-based business can be.

The power and success of a social networking site is not measured based on its revenue, which may be zero! It’s rather based on the size of its network. For an idea to become a successful internet-based business, you don’t need to build a space rocket. And you don’t necessarily need to make money with it. Youtube, Facebook and Twitter are good examples that support my point.

Social Bookmarking Sites

Today social bookmarking is a major topic in the Web 2.0 world, and there are over 20 social bookmarking sites with millions of users and 100s of millions of bookmarks. You can see the list of top 20 of them at: http://www.ebizmba.com/articles/social-bookmarking. These sites allow a registered user to bookmark a page; that is store a URL along with some additional information on the internet. But there is actually more to them than just that. So let’s look at this topic in more detail.

Problem with Browser-based Bookmarks

So why is this any better than just bookmarking a page on your browser; e.g. “favorites” in Internet Explorer (IE) or “bookmarks” in Firefox? The primary problem with this is that a browser based bookmark resides on the laptop or computer that you are using, where the browser is installed. So your stored bookmarks are in a physical file sitting on your computer file system. Now if I want to access my bookmarks from another computer, you are out of luck. The other drawback to browser based bookmarks is managing them and finding what you are looking for. In IE we can create bookmark folders and categorize them into these static folders. But then there may be links that we want to put in multiple folders, which cannot be done well. So as the number of bookmarks increase, their management becomes a serious problem. Firefox provides the means for tagging a bookmark which is a better approach than IE’s. This is also the approach used by some of the social networking sites.

Tagging in Social Bookmarking

Social bookmarking sites solve the bookmark management problem via tagging. When you bookmark a URL you define a set of tags along with it. You can define as many tags as you like. These tags can be anything that you want but many of these sites will actually make suggestions when tagging. You can define as many tags as you like. These tags define virtual folders that can be navigated later on. But since tagging is just a word association, a bookmark may belong to several of these virtual folders (each being a tag). When looking for a particular bookmark you can simply navigate your tags to quickly what you are looking for. Obviously good tagging practices becomes important here. If a bookmark is not properly tagged then it may be difficult to find it among a large number of bookmarks. These sites may also provide a tag cloud to help you navigate your bookmarks easily. In addition to tags, these sites may also allow you to define additional attributes such as description and comments for the bookmark.

On the Social in Social Bookmarking

More important than tagging in social bookmarking sites, is the social aspect to these sites. Just like other Web 2.0 wiki like sites, these are social, collaborative and networking sites where you can share information (profile, tags and bookmarks) with other users on the site. You can rate someone else’s bookmarks and comment on them.

Many of these sites such as Delicious and Digg  enable you to have a network by linking with other users and exchange messages with them. For example on Delicious every user has an inbox so that one can send a bookmark to another user or receive bookmarks. On Delicious I can also subscribe to tags so that if a bookmark with that tag is added I will be notified about it. Of course not all bookmarks need to be public. On Delicious I have the choice of making a bookmark private, a useful feature that is not offered by all other sites.

One of the interesting benefits of the social aspect of these sites is that at any given time you can see the hottest and most popular items because of the number of times it has been bookmarked, buzzed, digged, the ratings (like/dislike or thumbs up/down) and number of comments that a URL receives, are different metrics for how popular or important an item may be. So usually the home pages of these sites that are accessible by all without registering, make interesting sites to visit on a regular bases for the latest most popular and most interesting stories and news on the internet.

URL Sharing vs. Social Bookmarking

Though all of these so-called social bookmarking sites deal with storing and sharing URLs, there are key differences. Among the names that I have mentioned here there are at least two distinct types:

  • Post and Share a URL: Sites such as Facebook and Twitter are not really bookmarking sites. You simply post a link to them so that the people in your network can see it. For example in Facebook you send a link to specific people via a message or you share it by posting it to your “wall”. The same is true with Twitter. Many people use Twitter to share news (in the form of shortened URLs) with their followers. But note that these sites do not maintain a categorized URL repository. Depending on how active you are, before long the link that you post on Facebook or Twitter will be burried under more recent updates. It is not really practical to refer to that link later on (though you can do it as all past updates are maintained by these sites).
     
  • Bookmark, share, categorize and rank a URL: These are the actual social bookmarking sites where you post a URL and possibly classify and categorize it by defining your own tags (such as Delicious, Digg, and Google), or putting it in a pre-defined categoy (such as Reddit and StumbleUpon). These sites rank the URLs based on how many times a URL is bookmarked, favored, and commented on. When you go to these sites you can see the top bookmarks in various categories. Within these sites, there are some that are for link sharing with your network (e.g. Reddit, Yahoo! Buzz) while others such as Delicious and Google Bookmarks (www.google.com/bookmarks) are for saving your own bookmarks (which may be private) so you can refer to them later on.

Which Ones to Use?

The two sites that I personally use most often are Delicious and Digg. I specially like Delicious since it has flexible personalized tagging mechanism. I can define whatever tags I want in addition to the ones that Delicious suggests when bookmarking. It is more of a bookmarking site since it also allows private bookmarks. It also  provides convenient plug-ins for various browsers that make it easy to bookmark a page along with tags, and then easily access your bookmarks from its Sidebar, just as if they are the browser bookmarks.

StumbleUpon is another very popular social bookmarking site with close to 8 million users as of this writing. Like Delicious it also provides its own browser toolbar. It has pre-defined categories (e.g. photos, videos, business) that you can specify as the topics of interest.  You may either save a URL as a favorite or you can write a review for it. You can also blog right within this site. Similar to other sites you have a network of friends or subscribers.

Reddit is another popular social bookmarking site. It provides a way for ranking and sharing URLs. It has a set of pre-defined categories called “reddits” such as pics, politics, funny, and technology, which are essentially general tags. You can also define your own public or private reddit. On any bookmark on the site you can rate it (like or dislike) save it as your own, or comment on it.

If you don’t have a favorite one yet, you might want to try out a few. I believe different ones may appeal to different people. However I must say that I find some of them confusing and not as useful, intuitive and practical as others.

Hashtags in Twitter World June 29, 2009

I briefly mentioned hashtags in my previous post as a special application of tagging in Twitter (www.twitter.com) and numerous other Twitter-related sites. In this write-up I cover hashtags in more detail.

Hashtags are special tags defined as #<tag> that one can use as part of a 140 character string to define a topic for a tweet. Content-oriented people may think of a hashtag as a virtual “folder”, while journalists may think of it as a “channel” that one can tune to or listen in on. So I may tag a tweet with #BPM (for a business process management related tweet) or #job for a tweet on a job opening, or both for a job opening in BPM. Note that hashtags are not case-sensitive and can appear anywhere in the tweet. As a specific example, I used the following tweet to announce my previous blog post on metadata and tagging. Note the use of numerous tags (5 of them) along with a shortened link to the post in the tweet:

“my blog post on #metadata and #tagging http://bit.ly/xxQby #web20 #internet #technology

You seldom will see a tweet with so many hashtags. In fact most people do not regularly utilize hashtags. For one thing it takes time to look up the right hashtags. But for your tweets to have context and reach the right audience it is best that you tag them with the appropriate hashtags.

Special Hashtags

There are some unusual but popular hashtags that any Twitter user should know about. Here are a few of these:

  • #FollowFriday or #ff: Used on Fridays to suggest people to follow to your followers and to whoever is tuned in to #followfriday. For example, the tweet “#followfriday @BarackObama” suggests following President Obama, who happens to be very popular with about 1.6 million followers as of the time of this writing.
  • #MusicMonday: Monday is music day on Twitter. Used on Mondays to suggest music to your audience.
  • #fb: This one is a special tag in the sense that if used at the end of a tweet, it performs a programmatic update to your Facebook account status, if you have installed Selective Twitter Update application on your Facebook account.

Hashtag Directories and Dictionaries

So how do I know what to tag my tweets with, if any? Where can I look them up? How does one define new hashtags? Let’s answer these questions. There are several hashtag sites that provide you with hashtag directories and dictionaries, where you can look up tags and find the relevant ones you need, add a definition to an existing tag, or even define a new tag, look at trends and see the recent tweets on a hashtag.

Below are a few useful hashtag related sites:

  • www.hashtags.org includes a hashtag directory. It also tracks the hottest and newest hashtags, usage report on any hashtag and more. For example as I am writing this, #IranElection that people use to share information about the uprising and unrest in Iran following the election fraud, is one of the top tags being used. This site however does not provide definitions of hashtags.
     
  • www.tagalus.org or www.tagal.us is a wiki-based hashtag dictionary. You can look up the definition of a hashtag, and if a definition for a tag is not provided you can actually add a definition for it. You can also define a brand new hashtag and add it to the dictionary. Sometimes people make up a hashtag as they tweet even though it may not be defined. For example while many tweet with #BPM, it didn’t exist in Tagalus till today. I just created it.
     
  • www.tagdef.com is another wiki similar to Tagalus that provides hashtag definitions. However since these are wikis and evolve collaboratively without the control of a central authority, they tend to be incomplete. #BPM happened to be defined in this dictionary, while there are many other tags that are not defined here.

While many hashtags have obvious meaning as they are spelled out, many others are acronyms and shorts for stuff that is not easy to understand and decipher. For example I just noticed that #mw2 is one of the hot trends right now. I had no idea what that was but according to tagalus.com it stands for Modern Warfare 2, a popular video game. Another hot hashtag these days is #gr88 that often appears alongside #IranElection though its meaning is far less obvious. It turns out that it stands for Green Revolution 1388, the current year in the Persian calendar.

Note that you can make up your hashtags as you tweet. The system does not check for spelling, nor does it verify it against a directory. But if you want a bigger audience for your tweets, you should use well-defined hashtags. If you want to use a seemingly new hashtag, it is best to first check the directories for it and its related hashtags. If it is not there, then it is a good idea to define and add it to Tagalus (and tagdef.com) first before using it.

I will be covering more topics on and about Twitter in future posts.
