I think OP has a point, in that its an interesting way to explore the game. I've found some of my most interesting character options following ideas from the Wizards CO board.
That said, it can bring out the best or the worst in the game and its players. I've seen some very intelligent, thoughtful, involved role-players in the CO board; I've also seen the worst.
I wouldn't mind discussing the new rules and options in such a board, but I know for a fact it might bring out the worst in some people. As much as I like the idea, I'd be against bringing it here, as I sort of consider Pathfinder the last of 3.5 (and the best), and I'd rather see it explored in a less messy way.
