I wouldn't say it's that bad actually. I have a group of friends that I had all the way through high school who I still see now and again, although admittedly I see them less and less these days, and I only have myself to blame for that. The only chance I really get to see them these days would be Saturday nights when they hit the bars, but I don't really have the money to be doing that regularly, where as they all have jobs.
I have another set of friends who I met at university. I see them on a daily basis through the week for a good few hours each day. Although I don't do anything with them outside of university, due to me being about an hour and a half away by bus. It's not that bad though, since I am around them most of the week.
I don't think people you know over the internet was intended to be included in this thread, but I don't see why they shouldn't count. I speak to a few people that I've met over the internet (mainly from Newgrounds, actually) quite regularly and actually consider a few of them to be good friends of mine.
I don't really think my social life is that bad. Could be better but I'm quite happy with it.
