Ask HN: Looking for a list of web-based business models

These can be tech and non-tech (content etc) models. Ideally it would be nice to have a list or diagram of only the 'currently effective/lucrative' web-based business models.

why? I think it would be a great tool for people to take their idea and match it to the best business model, and one that is not out-dated, inefficient model, but a model that is currently profitable.
