alternative PPC resource?

[Gurtie]

Has anyone seen a decent ppc blog/forum which discusses less common methods - block bidding, spotting opportunities, the type of thing that Google and Whitehat agencies don't teach you?

I want to try and train some subversive thinking into some staff. I doubt we'll be able to use anything even out of our clients respective boxes, but it's good to get them thinking about things differently, I think.

I quite like http://www.ppchero.com/ but best of all is playing around and finding my own abuseable areas, as you well know Gurtie!
