Like many technical people, my personality naturally gravitates towards introverted behavior. I am very comfortable being alone for long periods of time, and in spending my day writing code or fixing bugs with just me and my computer.

But I also enjoy interacting with other people. It just takes the right 'community' to draw me out of my shell. There have been periods of my life when I was outgoing, because I was in the right environment (college, certain jobs, sports, etc.). Other periods allowed me to retreat into my own isolated world.

There just isn't a magic formula that produces the right kind of community that we want on demand.
