Actually, a couple of questions.
How do I suggest that tags be combined? For example, it seems to me that iPhone, iOS and iOS4 are all the same tag. (Sure, iOS4 might be 4-specific questions, but it's not clear that people use them that way, and 5 is due out soon and, a year from now, it'll be 6, 7, 8...)
I don't think I have the privilege yet but, regardless, once I do, are there guidelines for when to combine/not-combine tags? Is it just my personal sense of what makes sense, or are there "community standards" and guidelines about when to/not-to combine?
