But what if you have already done the site, got 1000+ users, got some press etc.

Yeah. Ok. you haven't got incorporated yet, but based on the man hours spent, isn't it unfair to give the late-coming guy 50%?

Well, in that case you might want to give the existing work a certain value (say 30%), and split the rest evenly.
