It's all volunteer, though those who apply and are selected will get fame and recognition when their Champion pages appear on the PalmSource site. According to the application, writing a Champion page should take 10-20 hours up front and will require updates several times per year. In return, you'll get direct access inside PalmSource and you'll receive $200 in gift certificates to boot.
I was fortunate enough to get the Champion page for Writing, Text Editing & Word Processing -- something I love to do with my Clié and Stowaway keyboard. I figured all this experience I have using a handheld for writing ought to be put to some good use. :-)
