This is throughout college, so add annoyance about normal college stupidity and a dash of escapism. Though I'm not sure what your age is, so it could be you're in that situation.
I don't find it particularly addicting either, but to each their own. I'd be willing to bet there are at least as many FB addicts as WOW addicts, though.
I guess different social circles are different and it probably varies by age group as well.
I find your comments interesting because it is so completely different than my social world.
I should also add that I don't find it addictive at all.
