There's A Simple Solution

Boing Boing have a link to Guruphiliac, which they describe as "highly-recommended false-prophet exposé site". It's a good idea for a site and it does seem to be quite well done, but it make me think that you could probably sum it up something like:

"If someone calls themselves a guru or believes themselves to be enlightened in ways beyond the norm, then they are full of shit and should be avoided as much as humanly possible."

It could just be me, though.
