This couldn't have come at a better time. I've been trying to work out a business model for the idea I'm starting to work on and while this information doesn't make the decision for me, it helps remind me of the variety of options out there.
I wouldn't call this a "terrific" survey; rather it's simply a breakdown of the percentage of the Webware 100 sites and how they make money. The sites in the survey are mostly dominated by massive companies - amazon, google, yahoo - so I'm not sure specifically that us startup guys who can't monetize a site with the flick of a switch can learn too many lessons.
I too had been searching for a list of various web business models. This seems fairly comprehensive in categorizing the models in use, but does not help in determining what has been successful. I'd love to see some analysis of the profitability of these models.
I wish they would have put the data in a simple table as opposed to a large, shiny doughnut.
