Just using my administrative freedom on this site and introducing another E2.0 fellow on this blog - Prof. Dr. Joachim Niemeier (XING, Twitter, Blog). As involved within the Wiki Wednesday Stuttgart Martin knows him a lot longer than me, but still - first time I got to know him was at the Dresdener Zukunftsforum 2006, where he - as the former CEO of T-Systems MMS - acted as an engaging moderator of this great event. This is also the reason why I asked him to do the moderation at our upcoming Enterprise 2.0 Executive FORUM. So give him also a warm welcome!
