My man.
I blame Ben Radford and Blake Smith for their Monster Talk podcast exposing me to the skeptic movement itself (though I had seen Ben on documentaries or read his articles before that) but it was Lew who gave voice to all the shit that was being shouted in my head. He's also the reason I curse so fluently.
Dr. Karen Stolznow, also on Monster Talk but also a host of Point of Inquiry, is the only Skepchick I like so far, and also a fine investigator in her own right.
Daniel Loxton is also a great dude. If any of you have kids, he does a lot of stuff catering to the younger crowd that you should check out. He also wrote a bit about the whole "Don't Be a Dick" debacle and its history that I found rather inspiring.
