Duplicate Titles needing improvement and/or closed as duplicate

Inspired by a similar question on meta.stackoverflow, I just did this database query on math.se, and found 81 pairs of questions with totally identical title. (Ordered pairs where id1 < id2, excluding ones where one or both of the questions is already closed.)

• In some cases these might be simple duplicates, then vote to close.
• In other cases one or both questions might have a bad title, then edit the title (and maybe a part of the question and tags, if you are on it) to make them better (and distinct).

To avoid bumping to many of those questions to the front page (pushing off new questions), you might do this editing once in a while, not all at once.

• So far as I can tell, the latter case is more likely. I would suggest a gradual editing, as bumping too many oldies annoys some people. Aug 31 '11 at 16:53
• Good point. I added this to the question. Aug 31 '11 at 17:12
• adding a user column would make finding duplicates easier, perhaps? Aug 31 '11 at 18:43
• @Grigory: Duplicates are sometimes also posted by other users. But here is the version with only questions by same owner. (24 pairs). Here for different owners (46 pairs). Aug 31 '11 at 19:09

In order to keep track of those duplicate questions whose titles have been edited, I copied the output from Paŭlo's first query here. It might reduce the number of duplicated clicks if the questions that have been dealt with are crossed of the list (using <s> ... </s>). (Should the consensus be to edit the titles at all).
