Recently I read a comment in the Political section about trolling. Based on my experience in the MacRumors Forums, I think that most participants do a great job of conducting simultaneously thoughtful and lively debates. I think trolling is more than a single post but a pattern of activity. And still you have the challenge of determining is this what the person believes or is his/her primary purpose just to stir the pot? It's not that easy to identify, but it is easy to say "troll' every time you hear something you don't like. So what do you think a troll is? And more importantly how do you distinguish a troll from someone who has valid criticisms? 1. "Invading Iraq was a huge error in judgement." 2. "You warmongering Americans attacked a country based on lies." Statement no.2 is definitely more incendiary. But is it a 100% troll statement? According to Wikipedia: In Internet slang, a troll is someone who posts inflammatory, extraneous, or off-topic messages in an online community, such as an online discussion forum, chat room, or blog, with the primary intent of provoking other users into a desired emotional response or of otherwise disrupting normal on-topic discussion.
