*edit* Uh, well, ankh beat me to linking to the Jargon File... oh well. ;)
I use troll in the classical sense. See:
http://www.tuxedo.org/~esr/jargon/html/entry/troll.htmlThe Slashdot trolls are practically nothing compared to *REAL* trolls. ;)
What you think of trolling is what I'm used to calling lurking (from "lurking in the shadows")... and if we banned everyone who just hung around without doing anything, the forums would be a very empty place.
