Social awkwardness?

Lately people I've been hanging out with have been commenting on others' social awkwardness. I had a lively discussion of the difference in connotation between "dorks", "geeks" and "nerds", and which was the preferable descriptor (conclusion: nerds, because that connotes a general sense of intelligence with a twinge of social awkwardness but in an innocent, cute way, vs. geeks, who are smart but only about a few specific things, e.g. RISC microprocessors, vs. dorks, who do not connote a sense of intelligence but just a general awkwardness and perhaps below average intelligence).

By all objective accounts, I realize that I can be considered somewhat socially awkward, or at the very least, shy/introverted. Very scientifically sound online tests have confirmed that I lean slightly toward introversion. I do have a hard time quipping with strangers or saying profound/witty things with people I don't know.

After ruminating on this a bit, wondering why I'm not like other people who can strike up a conversation with just anyone, anytime, I've decided I'm not so much socially awkward as I am socially ambivalent.

To put it simply, I just don't care. If I don't have a compelling reason to know someone, I don't see the purpose in trying. Just because I'm curious about what's happening on a street corner doesn't mean I will ask about it. If I meet someone that I'm likely never to see again, I will promptly forget their name (this is a habit I should probably change if I ever have political aspirations). To me, you are not interesting unless I have a reason to be interested (which is probably at least part of the reason why meeting girls at bars is not a successful strategy for me).

This will probably stymie me in any forays into business or general career networking, but for the moment, it's a part of me. Should I change it? I haven't decided yet.
