Dave Green has started his blog, welcome Dave!. Dave is the WWF Architect, and he's been having stacks of fun building out Microsoft's workflow platform, I have to say WWF looks really cool. Dave's a very smart cookie and has been building workflow engines for some time now, I'm sure he'll share some interesting insights around the workflow space. Dave, John and myself were the British faction in the BizTalk team before I defected back to Blighty!
