It's rather hilarious watching all you guys debate the invisible man. Invisible because I've long put him on ignore and I just see your posts with nothing between them. You guys should try it. The guy doesn't provide any insight beyond what the left emails to it's listserv every morning. It's not like you're ever going to get him to go "hmm, that makes sense" on any subject at all.
I'm not a big one for using the ignore function, but sometimes it's necessary to remove the noise and get more signal.
For being invisible he sure seems to get under your skin since you keep bringing him up. I've got half a dozen people on ignore, but I stick to the definition of the word.
