I am relatively new to vi.se, and over the past few weeks I have noticed that when I visit the Home page (https://vi.stackexchange.com/), often old questions will come to the top. An example is this question which, on opening, says that it was active yesterday. However, I cannot find any actual activity (no edits, no new answers and no comments since last year). Why does this happen?
On a tangential note, is the feeling of the community / mods that it is worth trying to answer such questions? On the one hand, it may help someone in the future. On the other hand, the original poster may not see the answer or may have taken a different approach, meaning that a potential answer might not attract the appropriate conversation to assess whether or not it addressed the original question (not looking for points, if that's what they're called, just don't want to be talking to myself in answering a dead question).
