Interesting discussion.. I guess it comes down to the people around you. I consider myself a pretty social person, although I'm pretty picky when it comes to people. But with those really good friends I certainly enjoy the company. I also sometimes love being alone, listening to music while having a nice walk outside can be so relaxing. And after being in work all day listening to people who you really don't care about, having that time for yourself can be just the thing you need.
But in the long run I need people around me. There's just so many things in this world that you get much more out of if you share it with someone.. and seriously, a nice long conversation with a friend is way better than some internet discussion
So you just need to find some good people around you. I gotta admit I wouldnt' spend more time than I actually have to with most of the people who I'm in contact during the day (people at work etc.)

Jam it back in, in the dark.
