Long story short: editing of wikipedia articles, if properly done, can inform the world and drive more traffic to paul's site. But just like anything, it takes doing. Editing wikipedia is not for the faint of heart or academically challenged, so if you have what it takes to do this, please consider contributing.
I was looking at Paul's wikipedia article yesterday, and was thinking how it needs to be updated. I tried sticking in info about his book, but MAN, that was kind of terrifying, so I totally stopped there!
Is there anyone on permies that likes/knows how to do this sort of thing?
