Strongly related: How do we deal with octuplicate questions?
This is not a question about how to deal with duplicates, it's a simple "meta" question:
What is the most rampant duplicate on Stack Overflow?
- The particular duplicate must be "alive" on Stack Overflow (not merged or closed duplicate)
- The duplicate-ness must be pretty unquestionable.
This is a duplicate of score
2 1. https://stackoverflow.com/questions/227662/what-is-the-best-editor-or-ide-for-ruby-developmentmerged ;-p
They are both so close that it makes little sense to have separate questions.
However, score 2 is pretty uninteresting.
(The rationale of this question is to find the duplicates so we can get the administrators to merge them. It is also to find better ways to find dupes in the first place, and perhaps turn finding duplicates into a game.)
