I don't even have an opinion on AG. I'm just saying that having "the idea of Facebook", and that you were the first to have that, is retarded.
First of all, it's a really really old idea.
Second of all, the idea is irrelevant. What made Facebook succeed was the execution. That goes for most of the other online successes as well. Selling books online, or search, aren't novel ideas. Amazon and Google, too, succeeded because of execution. They all did.
