I just noticed that when I edit my answers, for grammar, clarity or details I just thought of, the question get bumped to the top in the list of active questions.
This struck me as impolite attention-hogging on my part. Is there some way I can stop my edit from bumping the question?
No, edits intentionally always bump the question; it's part of the peer-review process that keeps the network well-groomed. As a matter of fact, there have been a number of pushes to get moderators that ability, and even they have been declined.
It's fine to bump questions with properly substantive edits, just try to rate-limit yourself so no more than ~4 posts of the top 10 on the front page are the result your edits.
