I just had a really annoying occurrence of someone editing my question. Essentially someone changed one word comprised
-> composed
. The edit summary (aka revision comment) of the edit was comprised != composed
... Now the editor thought he was doing me a favor and correcting my English, but wouldn't you know: I actually meant comprised
.
Right then and there I rolled it back - not a problem.
At the very least I'd have liked to put "no i meant comprised" in the edit summary for the rollback, but the summary was auto-populated to "rollback to rev x". (apparently this already exists...)
But I still think a full-blown comment thread for edits might be a good idea to facilitate the refinement of questions. Short of commenting on my original question there is no way to do this right now.
