Recently, I have seen a lot of questions that seemed to have no context or shown prior research, especially the old questions. Should we close them? Or leave them as-is as they are old? E.g. At this moment vs At this time; this question shows no effort of looking up the difference.
My two cents: feel free to vote to close if you stumble upon them, but don't go actively hunting for them. Closing a question is most effective before it gets an answer; afterwards, it's more of a reminder which questions are acceptable and which aren't. Because the Close Votes review queue is quite large, and has been so for a while, we shouldn't increase the workload too much.
