Its big, and has a large audience. That said, I don't buy the hype. Sure it could do this and could do that, an experiment like this will be lucky to work at all.
Also is rumored to have the possibility to spread new viruses accross the planet and a lot of other shyt. I am not a big follower or anything, I get all my info from a guy at work who is.
Sounds stupid, its a big grey area to me. haha.
