Who Follows Who is a very concise tool that caters for twitterers that want to have a better overall understanding of the scene as a whole, as through the site they can provide the name of up to five different Twitter users and see who follows who and the followers that they have in common. It is really as simple as that. Using the site doesn?t entail furnishing any particulars or credentials, so that even those who are a bit gunshy when it comes to sharing profile information will be able to put it to immediate use. While the service on offer is not revolutionary, it is a nice addition to your Twitter toolbox. If you happen to use and take a liking to it, do not forget to thank Mr. Janis Larkin (the programmer) and also provide any insight and feedback you might have. For one, I would like to see the number of Twitterers you can search at the same time go up from 5 to a number like 10 or 20. Just a thought. What do you think? http://whofollowswho.com/ bye.
