I thought I was supposed to go to area51.stackexchange.com to ask a sample question and see if people liked it or not, but I'm not actually seeing that functionality on that page. It seems like a place to propose topic ideas for the stackexchange. Am I mistaken? Does a question proposal site not exist? I don't like getting thumbs-downed, so I want to propose my question before asking it, especially at the heavy-downer sites in the network.
Additional details: I would like to ask a follow-up question for a feature request. Where's the best place?
