I've knocked a couple of questions off that list, but still, we are in a much worse state than we were when we left beta. IIRC, we had around 40 back then.
The reason for them seems to be the drive to move [latex] questions off SO if they do not involve non-Tex programming aspects. Many of these questions are abandoned, poor quality questions that were unanswered on SO. The typical pattern for them is that we receive them, they get a comment or two asking for clarification, but the asker never turns up here, so they languish unanswered and unanswerable.
I'd like to tackle these questions. I propose to flag for moderator attention questions of this sort with a comment based on "Ill-posed and abandoned migrated text", and add a comment to them linking to this meta thread. It would be appropriate then, assuming I am right in my assessment, for a moderator to close these questions as "Not a real question".
An alternative course of action would be to vote to close these for the same ground. The advantage of going the flag route is that the flag text marks these items out, and so allows them to be dealt with a bit more expediently. I don't plan on spending so much time each day on these items that they would unduly clog up the 10k+ dashboard, but that might happen if several people joined me in this effort.
Is this a good plan? The prize is to have a useful unanswered-questions list again.
