> takes a certain amount of chutzpah to hear about all these eminent people saying "This will be the next hot thing, you better get in now!" and think to yourself "Actually, sounds like bullshit to me."

More of a personality thing. If you would pitch Dropbox or Facebook to me today, I would consider it bullshit just like back then. Nice little niche maybe but certainly no Unicorns. Who would put sensitive personal information into the cloud?! Obviously not much of a market.
