Essential strategies for creating a successful web product from Dion Hinchcliffe

There is some excellent advice from Dion Hinchcliffe in this article outlining '50 essential strategies for creating a successful web 2.0 product'

Although web 2.0 is mentioned in the title I think these ideas could apply to most online products, especially "start by solving a simple problem".

I have a feeling that this is one of those reference articles that I may have to come back to from time to time. Its a great checklist.
