The main utility of the my reputation (aside from ego ;) seems to be that it can help get questions answered if I add bounty to them. I'd like to do so on deserving questions, but I don't have the time to find & choose them.
A rough idea of what I'd look for: open for a significant period of time, the questioner is still active on the site, and it's a "good question." To me that would mean: it either asks about a specific issue a lot of people experience or one where thorough answers would be a useful learning experience for a broad audience, even if the specific situation is narrow.
Is there some bounty pool I could donate reputation to? I don't mind trusting the discretion of others in the above.
Failing that, maybe there could be a "deserving question" tag or list?
And a third, fallback, option: Link me to some good questions! ;)
(Musing, a bit maybe this could be a new feature idea: "Donated bounty pool" -- a questioner themselves could choose to add some fixed amount of donated bounty to their question themselves after it's received some upvotes & remains unanswered for a period of time.)
