Love him or hate him, there's no denying that Robert Scoble was a major player in changing the face of corporate blogging. He did more as a blogging employee for Microsoft than any other PR endeavour they have undertaken to date.
It sounds like Scoble's duties at PodTech will be much the same as when with MS - Corporate Evangelist. This is a huge boost for PodTech and, by extension, for podcasting in general. Scoble's star power will bring a lot of attention to the media.
