Biggest and most single minded, maybe. But certainly not the best. I know of trolls way more skilled, and the absolute best are the ones I can't even catch a sniff of.
True, a really skilled troll will suck people in in a more subtle manner. I've been on the internet since before the 'web' even existed. Most interactive activity took place on listservs and newsgroups, and I've seen all kinds. Our primary 'tech troll' does seem to have the ability to engage people here from its sheer bloody single mindedness. People don't want to leave the uninformed to think that he may have a point. Personally, I just really don't care about such things beyond pointing out the fact that it uses this conservative political forum here on FreeRepublic for its own amusement.
I'm sure I'm not the only person who noticed how much more pleasant the tech threads were during December and the early part of January when the resident troll was apparently otherwise occupied. If you look back through the threads, there were disagreements about things, as is the natural course of things, but it was much more pleasant, as people were interested in contributing to the threads, and not just picking a single point to drive the thread down his chosen path to eliminate any signal present and drown it out in complete and utter noise.
