Could Wall Street end the new .com party?

It's 2007 and there are a bunch of no-revenue, good idea, 2.0 Internet startups out there that haven't really spend too much time thinking about their business model. The secret (or not so secret) hope is still that Google or Yahoo will come in with a bag full of cash. Henry Blodget the famed former analyst who predicted Amazon at $600 has an interesting opinion on how a Wall Stret crash could end the party. It would definitely deflate some of the valuations (Youtube anyone?) but probably not have a major impact. For you startups out there- think about the revenue model, not the Goohoo money.
