Lenn Pryor, who has the unique roll of being Robert Scoble's manager, recently switched to dasBlog. Jeff Sandquist, one of Robert's co-workers also switched over from Radio. He posted a nice How-To on moving from Radio Userland to dasBlog (importing posts, comments etc). It's a little known feature that dasBlog can actually move all your Radio stuff over, as well as continue to upstream your posts to your Radio site (via upstreaming service) as well as map your Radio links to dasBlog links using custom http handlers. Clemens (dasBlog papa), myself and a few others actually moved from Radio to dasBlog using some of these tools.
