if they are buying here, big boys aren't concerned about valuation (like Amazon). As long as FB keeps up the mobile growth story, and keep in the news/headlines, then it will continue gain new investors. I hope it goes down a bit to buy more though.
100+ implies 120 billion mkt cap, like an Amazon - that is tall order. I'll be happy at $40 first where there is probably a decent amount of resistance from people losing on IPO. I think we might dip back to high 20's and I hope they miss on earnings to pick up more. It has gone straight up in 3 months. For good reasons though. I just like to get more before any Twitter IPO comes into focus because then you know FB will run ahead.
