I have to say that this question is very broad and have been discussed often. It is always an interesting topic and share experiences is good but I think that it would be better if we could narrow it a bit more... what kind of experiences are we talking about? customer related (meaning how to get paid, how to treat the customer)? Technical issues and best practices?
Same with the tutorials... what topic exactly?
Maybe you should be a bit more specific or give us an example to get started.
