A few minutes ago I changed one word in an answer from years ago and I noticed the post (which was closed, in fact) was bumped to the top of the active tab. Is that something that's really desirable and/or is that something the community has any control over?
Meta Meta has long discussions of this feature, see The problem with automatically bumping edited posts and its predecessors, including its use for spotting malicious edits, complaints about "deliberately bumping posts", and requests for "minor edit" marker that would prevent the bumping. Here is Servy's surmise:
"If people don't want to look through recently edited posts, and only want to see newly posted content, they can use the "newest" tab rather than the "active" tab. If they're using the "active" tab then it means they specifically want to see questions recently bumped in this manner."
