Yes, my primary reason for being so much on here in the past was that I had no one to turn to in real life, and there was nothing I could do about it at the time.

The other reason I can think of would be nerdiness, and there's a lot of nerds here come to think of it. Me included. Sometimes.
“I have long held the opinion that the amount of noise that anyone can bear undisturbed stands in inverse proportion to his mental capacity and therefore be regarded as a pretty fair measure of it.” ~ Schopenhauer
