Who bought Facebook (fb) stock today?

I finally placed a Limit order last night. Not enough to make or break me, but I wanted to be in the "game" It was supposed to start on the Nasdaq this morning at 11:00am, but didn't start trading till 11:30 due to glitches. It was supposed to start at $38/share, but opened at 42-43. I placed a limit order on 40. Now trading at the 38 mark. I'm hoping it's my next AAPL stock that I bought 3 years ago at $75 and now trading at $538.00
