I've always kinda lurked in usenet but for the last 6-7 months or so I've been lurking in comp.lang.lisp (it's a programming language). A frequent poster is this nutjob named Xah Lee.
His posts are horrible. They add nothing to the discussion, they are filled with the most insane boasting, and they make no sense whatsoever. But I love them. They are usenet car wrecks.
Here is Xah Lee's site. It's fucking insane.
