You know what the geo blogosphere really lacks? Gurus. Seasoned, opinionated, frankly critical, highly credible people writing about implementations. Experts in technology or methodology, writing with good style, clarity, and a sense of humor. Where are our Martin Fowlers, Tim Brays, Paul Grahams, Mark Pilgrims, and Joel Spolskys?
Geoff Zeiss has potential. His photo reminds me of the older fisherman I'd see back when I was a hack fly-caster. The kind of guy who could step up to a hole that I'd whipped fruitlessly to a fine froth, and tease out a trout on the first cast. But he's expressing the Autodesk viewpoint and not implementations in general.
Don't be fooled by his twenty-something looks (on display in his blog banner); Ed Parsons is a seasoned industry vet. He's written some provocative posts, but identifies more with CxO bloggers than we techies.
