Why are members' locations so important to you?
Glad you asked!
Caveats: It's none of my business, and, most of the time, it matters to no one.
But: There are a number of times where one's location being absent is a detriment to the meaning of a post. e.g., when talking about cable companies, or weather, or gas prices, or local shopping options, etc.. Oh, and personally I like geography and sometimes it helps to understand where a poster is "coming from".
I get that some think it's perhaps an invasion of privacy; some won't do it simply because they've been asked to; some think their entry is amusing; whatever.
