Two questions have identical titles:
The URL's are also identical:
Well, not quite! They have different numeric identifiers, at least I assume that is the purpose of the number in the URL. Note also that the question content in both is similar in meaning, although not identically worded. Why isn't this a bug?
I just noticed that the questions were merged. However they both were displayed in a list of similar questions, one beneath the other, on a recent regex question (sorry, I should have taken a screen shot).
If questions have been merged, should they still display separately in the related question column?
EDIT #2 Sorry it took so long. And kind of fuzzy!
