I just came across a question on the front page of Meta from 2008. This happens about once a month. Heck, it might happen more often but I only notice when the question is wildly obsolete. Often it asks about something that was implemented 3 years ago, in a vague "should we have this sort of thing?" way that is anachronistic now.
I worry that people will comment and answer on something that has been over for a long time. I worry that people will form an inaccurate opinion of the current state of the system. I'm mildly annoyed that I got sucked into reading something that is obsolete and not important. And why is this happening? Because someone fixed a spelling mistake or other tiny issue in a post that was otherwise long dead.
Now don't get me wrong. I'm not arguing for there to be any kind of non bumping edit. I've argued against non bumping edits before and will again. But after I've read it, and ascertained that all the answers are from 5 years ago and all that's happened is a minor spelling fix on one of them, could I please somehow unbump the question? So that it no longer is on the front page?
silence link, after the post that was just changed, next to the edit/flag/share links, would be great. If necessary, require some number of them and show progress like with close:
unbump(1) would work for me. Make it 10k or 20k, make it the "what should be offer people who get past 20k?" rep, heck make it diamond only and I'll flag to ask them to do it. But please, can we make the obsolete stuff sink back down to where it was?
