My thought was that it would be more like a reference, not a discussion. The entries would be concise and to the point and well-structured. It would be as if someone condensed the Cocoadev discussions on a topic into a Wikipedia article. I don't care who said what when, just what the final conclusions are. Maybe a Cocoadev subsection?
