As it is only natural for something that constitutes the essence of Twitter, there is an endless number of tools aiming to let you know whether or not a particular person is worth being followed or left to his own devices.
In this particular case, Foller.
me aims to provide users with comprehensive information in as short a span of time as possible. Upon furnishing the screen name in question, you will be presented with profile information and (the most interesting part) a selection of the most representative excerpts from that user´s latest 200 tweets. Three different clouds are duly produced: “Hashtags”, “mentions” and “Recent Topics”.
This solution seems to address a common concern for tweeting adepts: while reading a representative number of tweets generated by any user would be the logical thing to do before starting to follow anybody, that is downright impossible for the mere fact that we always have better things to do. Having access to a sort of “Best Of” collection of tweets is certainly interesting, and that makes this site worth a peep.
