I think it's because forums are asynchronous and low-commitment. If you find a conversation tedious you can just not reply. Harder to do when you're involved in an in-person conversation with someone. The cited definition from Wikipedia is rather vague and I'm not sure it's entirely accurate. I've always understood introversion vs extraversion as being about where you derive social energy, rather than gratification. I consider myself an introvert. A weekend spent socialising with friends is very gratifying to me, but it is also exhausting, and I am likely to want to spend the next weekend chilling on my own.
