I like Logan's idea, because if we take BdB as an example, trying to choose one of his creations he enters into a GB, it's very hard.
But there's another example of a character on another forum who loves to swamp a GB with a bunch of projects, and while his ideas are generally very interesting, the execution of said projects are a lot to be desired. But on occasion he does do a real cracker, so Logan's idea doesn't really work here. I thought the idea of voting for a particular subject is because it really creates a stir as to how it appears to the person looking at it, the others might not.
Just my 10 cents worth ----
