I think this will be a great format. Frankly I’m sick of all the forums – rpg.net, enworld – with their ubiquitous moderators with an axe to grind and demented clique politics, and full of nimrods making self-congratulatory off topic posts. With Stack Exchange, everyone gets to vote on questions and answers so the good discussions and ideas float to the top. And it’s focused on the question/answer format, which is very useful for, you know, questions and answers – in forums those often get mixed in with other stuff.
So go vote for it!
