Of course there's going to be an overlap, amplified even further because most (non-technical) people will ignore the difference between the two. My point was that the two communities' lack of support for the merge is not really an application of "the narcissism of minor differences": the overlap exists, but it is not that important, at the moment. Perhaps in time, such a merge will be justified and users of those two sites might acknowledge that. I hope this clarifies my first post for you.
