Previous questions have dealt with similar issues:
1. Is there anything we can do about ancient questions being bumped?
Conclusion I: Valueless questions getting repeatedly bumped is a problem. They should be closed.
Conclusion II: It's a good thing that old questions get bumped; maybe someone can find them useful or answer them.
2. What should be done about old, abandoned questions?
Conclusion: Very old, drive-by questions with no lasting value should be closed. Downvoting would also help.
3. Should we close old questions with no more feedback as "no longer relevant", on SuperUser?
Conclusion: Such questions should be closed.
This question:
Excel-matching row order in two spreadsheets
Has been getting bumped every 4 months, apparently:
It does have an answer - it's not a very good answer (it's not a very good question), but the querent evidently found it helpful - helpful enough to comment, though not helpful enough to mark it accepted.
Does that mean I'm going to see it bubble to the top of the active questions list every 4 months from now on? It's not off topic, and it's not overly broad, it's just not a very helpful question. I don't know that it should be closed for that reason, but I do know that it's not doing anyone any good getting bumped until the end of time. If it can't be closed, can it be marked as answered?
