Twitter is Nothing

As far as I can tell, Twitter is absolutely nothing. Is it a stripped down Facebook that is reduced to nothing but the iLike application? Does it achieve anything other than people's desperate attempt to have their name somewhere else on the Internet? Is Twitter anything? I like the Vanessa Carlton song "1,000 Miles," but I don't necessarily want everyone in the known universe (or at least those planetary systems with decent wireless reception) to connect me as a fan, shit, I don't even want my close friends to know that. This will mark my attempt to delve into this concept and research as closely as possible as I can (the Internet is a fifteen-minute bike ride or thirty minute bus ride away) while holding to the above post title as my hypothesis. If you think that Twitter might be something, or even something else, please feel free to respond to this post because after all, Twitter might not be nothing at all.
