A while back, I proposed a books.[so/su/sf].com for books reviews and such. The common suggestion was "make it a hosted version". The general idea in this hosted version was that each "question" would be a book and some metadata (author, title, image of the cover, ISBN number, links to booksellers, etc) and the "answers" would be reviews that could be voted up or down based on helpfulness. Then Stack Exchange came out - it could have been done with SE1.0 when you didn't have the approval process. But now, Area 51 stands between an idea being proposed and actually being given a Stack Exchange.
I'm a bit busy now between work, my own proposal on Area 51, the 2 closed betas I'm involved in, and my 1 commitment that's still waiting for beta. But I wanted to ask the community - how can I actually get this through the initial stage if I (or someone else with more time) were to propose this on Area 51? There aren't enough on-topic/off-topic questions and what is and is not acceptable is very well defined with very little (if any) gray areas.
