I've been doing a bunch of digging around to help solve our accept rate problem. It's probably a multifaceted problem so I thought I'd tackle this one for now. According to meta, our policy is to vote to close as Not a Real Question (though Too localized seems to make more sense, but whatever.)
Finding abandoned questions is easy, Oli even has a nice web tool that does this for us. The problem is once I've voted to close there's no way for me to get that question on anybody's radar unless I:
Post it in the chat channel and hope enough people are around to close it.
Flag it for moderation, which means then the moderator's supervote can close the question too easily, and adds a task for them that the community should be able to easily handle.
Edit it in the hopes that the bump will get it in front of other high rep users who can vote accordingly.
In the review page I can see incoming vote closes, but not everyone has access to that, and it feels like there isn't a core group of people doing that (though I do it every day).
So, my TL;DR problem is, anybody on the internet can come in, post a question and bail on us. That costs them almost no effort.
However it takes us seemingly a much larger amount of effort to undo this, and it feels like we're losing this battle. So how can we make this easier?
