Something I've noticed about the current trend for videoblogging is many good writers fail to provide two things, quality and content.
Technical quality is tricky, limitations include hardware and, especially if using software like Qik, software. You wouldn't expect everybody to have this in place, to be honest, - it's hard work making things look good.
As for content - video is made to be seen, so self-indulgence, which may be interesting as text, really doesn't come across to a viewer. You need a point, perferably something the viewer cares about.
Personal writing works, personal video does not.
