Ever since starting to engage in the blogosphere (and Facebook, and anywhere on the Internet, really), I have frequently encountered the phenomenon of "trolling." Wikipedia's definition of an Internet troll is "someone who posts inflammatory, extraneous, or off-topic messages in an online community...with the primary intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion." I think this is a fairly adequate description of what so many of us have experienced with disdain. I am not sure though that these frustrating people who like to antagonistically comment on everything are always doing so entirely intentionally. Sometimes, I think people actually think they are responding intelligently to something or engaging in a legitimate discussion when in fact they are not at all.
