They really liked this Panasonic, which looks like it would be a cool videoblogging tool, too. I have to say, though, that for videoblogging the video capabilities of digital still cameras are looking pretty good. My little Sony pocket camera shoots 640 x 480 30fps video, with shockingly good sound. And I shot all the video for this piece using still pocket cameras -- a Sony and (for the underwater parts) an Olympus.
There's even one that shoots in HD (1280 x 720 pixels). That's overkill for videoblogging, of course, but it's sort of cool.
