Congratulations. Great PR strategy there, using a timely news story to get covered.
The product itself looks great, and the TC article did a much better job than average in explaining why the big companies won't be successful building this.
Let's see, Eduardo invested $30,000 in Facebook? And he's perceived (so he can borrow) to be worth over three billion now. So he can afford to invest $30,000 again about 100,000 times. Maybe he'll hit again. I'm not sure his investment is something to brag about though. He doesn't look good right now. Many folks might avoid his investments because they think he is disrespectful and immoral.
Fuck that guy. edit:(Good for you though)
