I've been reminded several times that a question on a SE site should be able to help future visitors. Indeed, it's very common for a question to be closed for being too specific.
At the same time, we all know that duplicate questions are of the devil, and should be closed immediately.
Both of these lend themselves to the notion that an answerer should maintain their answers: They should be applicable to as many people as possible, and prevent the need for the question being asked again.
This works great for me, as I'm the type of person who returns to his old questions to tweak and improve them as I learn more. I enjoy having that control, and crafting my answers -- and it's not uncommon for me to tweak minor things like layout and wording.
Unfortunately, I've recently discovered that my passive tweaking bumps the entire question to the top of the active questions list. I've been told that this is done to help the community flag spam. This doesn't bother me at all, but I've found myself being scolded by certain community members for "deliberately bumping posts" (which is simply not true).
If some people don't like people editing their posts, and it irks them, is there a better system that would encourage the maintenance of answers, that wouldn't annoy these people?
Proposal: There be a "minor edit" button like Wikipedia has? These minor edits would check for formatting changes by the original author only, so they wouldn't get bumped to the top of the Active Posts list.
