Clearly editing a closed question with the intention of making it re-openable is an honorable activity. I'm wondering more trolling-type questions (which we get a lot of!) Things like:
And dozens others that I can't find now, probably because they were deleted.
Is it worth while to edit these for grammar, spelling, etc... and perhaps most of all, is it worth re-tagging them?
EDIT: Part of my question is, are tags useful on closed questions, and therefore should retagging take place on closed questions? I suppose this would be for the purpose of searching, etc.
