Regardless of your opinions on whether or not app.net is a worthwhile endeavor, I think Dalton is proving that the "pay for service" business model still does exist and can be applied to internet services. For so long, the norm was "build service people use for free, get a million users, figure out business model" which inevitably leads to a) selling user info or b) targeting people with ads.

Constantly trashing app.net is not seeing the bigger picture. Thankfully, people like Dalton aren't as short-sighted.
