Interesting implementation. I tried to build a social code site (http://www.usethesource.com/) but it didn't really take off.

Why this method of voting works so well for photos on likebetter.com is that you can make split second decisions. I'm not convinced that this would be all that "fun".

It would be cooler if it integrated with http://codepad.org/

I don't know if I love this or hate it.

Sometimes I'm afraid if I look at enough "slack code", I may go blind.
