Every day I take 20 or so votes and clean-up old unanswered questions in a particular category. A surprising number of these are with deleted users, self-answered, or actually have answers that were never accepted or up-voted. A simple up-vote to a deserving answer takes it off the list.
To be clear, I'm talking about voting on actually resolved questions, not up-voting just to remove it from the unanswered list. This means the question has an answer that solved the issue, but the original poster never accepted, was deleted (wasn't moved with th question?) and no one up-voted the answer either. For this to work, you would have to know the topic, which is why you could only do this in tags you have expertise in.
What's the best way for the community to handle these? I can only cleanup a category about as fast as it grows, keeping the unanswered count about constant, but if the community focused on cleaning up a particular tag a time (or maybe just more votes used this way in general?), it seems we could assign rep where it's due and close out a lot of these old actually resolved/answered "unanswered" questions at the same time.
What's the best way to organize something like this, or is there too little interest to do so?
My only thought was a simple question here on meta that has a "tag of the day" to clean up (only up-voting answers that resolve the issue, not just up-voting to close of course) or something along those lines. Or... am I just crazy for not wanting those unanswered questions to hand around?
