Many approaches have been taken to using Twitter (the popular micro-blogging service). Some choose a minimalistic approach, following only users of interest and keeping their “tweets” simple and effective, or choosing rather to listen more than to tweet.

Others, however, take a more, shall we say, active stance on Twitter, following as many people as possible, in the hopes that those many people will follow them in return, creating a larger network of users that may view their tweets.

Bring on TwitterLeague, a service (recently out of beta) that creates groups of people (leagues) competing for the highest follow count. Users use their Twitter login information to login to TwitterLeague and create leagues of users in their stream, allowing those users to take part in the “competition”.

To illustrate how TwitterLeague works, I created a league below of Capetonian tweeters and added Capetonians from my Twitterstream* to the list.

* If you want to be removed from the league, or are not from Cape Town, please give me a shout via Twitter DM or via the contact page to be removed. Also, if you would like to be added to the league, do the same.

Twitter’s API has been used extensively by a variety of services, from applications to monitor your Twitterstream, all the way through to an exclusive “hot or not” style website for the Twitterverse. TwitterLeague is another interesting use of Twitter’s API. I’m interested to see what comes out next.

Have you used TwitterLeague or any other interesting Twitter services? Let me know your thoughts in the comments.
