So, you've taken the time to wander through a certain blog or website, and you see something that ticks you off, and they've got an open comments section. What do you do?
If you're a reasonable, sane and normal person, you might make a comment directly relevant and factual as an attempt to correct and/or address an issue. Or, you could take the easy, obnoxious, juvenile path and blast out a non-sequitur laden, grammatically incorrect and ignorant bucket of blargh -- i.e., be a troll.
It's a good think there aren't any trolls lurking around this blog!
