So I thought it was an interesting look at what I'd consider 'second tier' web sites. But really they are filling the role that is the 'enthusiast' magazine or newsletter.

What this analysis misses is a storefront for a painting company. That is all about lead capture and closing the deal. Harder to quantify. Well, easier for the store but harder for third parties to quantify.

So clear business models for client relationship management and review type editorial. Less clear on 'newsy' type sites or reference sites. Game/App as web service seems pretty clear too as a model.
