I was thinking about this yesteray. How it is pretty much a no brainer to use hacker news to market stacker news. It was the old school message board way. You like this so you might also like this.
It is also a no brainer that a sports version of stacker news be created. There are a bunch of sports message boards that it would be easy to subvert their guidelines and promote value for value model. Once people go sats they don't go back.
