I'd like to suggest not to bump a question if there's only some text editing happening. I see this frequently (using the RSS feed) that questions appear there which are years old, just because someone refined an answer, fixed a typo or something. This is adding quite some noise since I frequently start looking at the question even though there's no additional input necessary.
Didn't expect that this could really be something people want, but ok. So, is it possible to get RSS feeds for tags which include only new questions?
