I think the Tag Wiki block that Iain pointed out ( https://meta.serverfault.com/questions/1631/ways-to-improve-the-quality-of-questions-concerning-some-tags-tag-triggered-sug ) is about the closest we're going to get on this --  Might be worth raising on the new Stack Exchange meta once it's live though.

I'm basically just throwing an answer on this question so we can knock out one more unanswered question on Meta (no devs have looked at this in 3 months, I doubt they're interested :-( )
