One of the other things that I like most about interacting with people on the internet is that the social interaction occurs in manageable chunks, at appropriate times.

I am an introvert (INTJ, if you are into that MBTI thing or whatever it is), and social interaction tends to exhaust me a lot. But the internet is cool for that specific dose of socialization, without over-doing it, and then I can go back to being a hermit and doing hermit things. Lol.
