Currently, comments don't bump a question on the 'recently active' questions view; only edits and new answers do. Comments also don't notify anyone except the question/answer owner they are attached to. As such, late comments are more or less invisible except to the affected users.
I hear that there's a feature that displays activity for partaken questions on the user's profile page, but
few people here probably visit this specific page but instead rely on the (much more visible) notifications, and
it doesn't actually seem to work for me -- or I just am not looking at the right place.
Someone may leave a late comment on an older question that inspires someone else to write a new answer from, say, a different viewpoint. (Or leads to a new question.)
It would therefore be nice for comments to cause questions to be bumped. There is not enough activity currently on this site for this change to cause chaos. Typically under 20 questions + answers + edits per day, combined.
Is this idea any good? Can it be implemented?
