Contrary to what certain podcasts are saying WebDD is not being organized by Microsoft, rather it's Dave Sussman and I doing the lot.
Microsoft have kindly donated the space and events management staff for the day but they've had no say in the speakers, agenda or anything else to do with the conference (oh - they're also paying for the butties and coffee all day, but that's hardly some evil Microsoft plot to poison everyone who attends the ROR session...).
This is a conference BY community FOR community.
