This is the more common meme, and I think it is healthy to keep 'idea folks' away. Even great ideas, without execution, are worthless.

But as you say, a great idea combined with a great execution is where things get really special. Still, I do think great ideas are rare. It depends a bit on how you define what an idea is: is it a social network? is it a social network within a college campus? is it requiring real world identity?

The idea was 'a place that people will call their home online', and in the initial phase of FB my guess is that it was a place where you could find potential mates and a way to get introduced to them.

Do you mean "mates" in the British pub sense or in the David Attenborough sense?
