Stop talking, start writing! Seriously, if you can do it in two or three days, what are you waiting for?

These guys are experienced businessmen and have analysed and guessed that they can charge $$$ (per month!) for StackExchange and that it will be a success.

If you can put out a clone and charge $$ for it (one time), and allow people to host on their own servers (which StackExchange disallows AFAIK), I'm sure that people will be interested.

Seriously though guys, I don't think it's that difficult to do in a week. Simply because; you've already got a perfect specification and model in StackOverflow. You've just got to copy it and every single feature until it works exactly the same. You even have an open source (CNProg) copy available for code reference if needed.

Do it, I'm waiting for a thread on HN from you and from ktharavaad on monday.
