I don't get why this guy was voted down. The truth of the matter is, the old guard always remains, they just become irrelevant. Facebook won't die, but it also won't be cool and consume your life -- the same way AIM isn't dead, but it's not like you sit around and think "they're reading everything I'm writing! It's only a matter of time before they make billions off of this!"

In fact, to this point -- I remember that, when Friendster first started, the founder's goal was to sell the company to AOL for something like $100M. This was why he turned down the Google stock.
