Bumping it up because of a new vote probably isn't worth it (doesn't add anything new to the people who've already read the thread), and edits are usually pretty minor. But bumping it because of new comments would let people know there was still discussion going on.
After contributions from a number of us (by random example here, here) over a number of months, particularly User:wmoore and User:tommccabe (and all happening before User:Yvain's work here, so we missed those ideas) we have a discussion area.
Discussion, including discussion of the discussion area, is welcome.
