Briefly, Technorati has released a new service - WTF - which appears to be a sort of cross between user created content/answers and a vote based recommendation system. The idea is that users enter topics (like the subject of a post) and content (like the body of a post) on something that they believe is hot. Other users can then promote these posts by adding 'blurbs.' What I think is really happening here is this: Technorati would like to increase its user base. In the online world, a big user base is a huge asset. To join in the WTF fun, you need to sign up with Technorati.
Personally, I'm not getting a clear signal on what this is, who it is for and if it will be successful. I mean, WTF? The system looks like a community blog.
