In all cases, these startups will have a business model that revolves around an old-fashioned idea that will, imho, once again become fashionable -- the customer. People pay the company for a service they provide. This has all kinds of good side-effects.

It will help the economy straighten itself out and start creating products with obvious utility. Most of the scams that are supposed to be businesses turn out to not be all that lucrative anyway.
Everyone wants a way to associate a name with a net resource. We've been arguing about this for a long time. Yet, all the time we're debating, we're using one that works perfectly well, operates at Internet scale, and has a proven business model that generates real money. It's called the Domain Name System.
