Often when searching Stack Overflow I find duplicates of questions. Dutifully I mark these for closure. But today it crossed my mind, surely other people are finding these, but they aren't being closed! Then I realised / remembered, close votes expire after 4 days.
So what then is going to happen to these old questions - will they stay in dupe land forever? I'd like to see them merged together into an excellent resource on the topic but this needs to be flagged to a moderator for action.
Surely if a question is flagged as a dupe often enough over time, this should show in the UI or it should automatically be flagged to mods? It seems like a waste of time to mark dupes for closure after about 24 hours once they've dropped off the various 'new' lists?
