He doesn't take himself too seriously. Whereas many see him as a troll, I think he's a true contrarian in a sea of fashionable contrarians.
It's a pretty........... interesting read. http://www.metafilter.com/102472/How-to-Get-a-Real-Education...
Good thing PG only updates his footnotes when people "misunderstand" him.
I can't tell if he's using the plannedchaos accounts on various sites to seriously defend himself by proxy, or is it that he thinks the Internet is a load of pixels on a screen that unlike some of us he just doesn't take it very seriously?
Edit: somebody commented below that Scott is now a professional troll, and I'm inclined to think that they're probably right!
