I was just reading some posts this week where someone asked a question and at some point in the responses someone called them a troll. The questions seemed to be pretty standard ones... where can I get a kickstand, etc., but were not typical of that particular forum. In other words, the kickstand question was in the roadie forum, not in the touring or utility forum. But there have been other times I've seen people called trolls that I was confused by, because they seemed to me to be honest questions or opinions. I think the definition has become a lot more subtle than, say, going to the C&V forum and writing and essay on the marvels of Carbon Fiber compared to Steel.
Plus, I don't get the "troll" bit. I had always thought it was like "trolling for trouble", but it seems it's a noun, like the troll under the bridge.
