Well I remembered his name, so the "Shawn who?" seems rather out of place. Shawn Fanning's place in history is irrefutable, I suppose.
What ever happened to Shawn Fanning? Nothing. So why is wsj doing an article on him?
rapture - which is a gaming social network is his next big venture, in addition to his work with snocap
Without reading the article I'll say: 1) snocap, which does decent business with myspace and other social networks to sell music, 2) rupture.com, a WoW gaming social network
Now that I've read the article, it appears snocap is trying to tag and secure music sales online and no one uses it.
