I feel bad for you PhDs. in Physics to have to waste your time reading crackpottery. Well, no job is perfect, everything has a downside, what can you do about it? Nothing really. Hopefully the "amusing" aspect counteracts the "annoyance" factor.
While John Baez' The Crackpot Index is amazing in its own right, are you aware of another AMAZING one by Dr. Warren Siegel of SUNY's dept. of Physics?
It's called "Are you a Quack?" and can be accessed by clicking on this sentence. Good stuff. :-)
