A lot of videobloggers started with Blogger. It’s free, and though you initially had to hack it a bit to get a video to display, it’s pretty easy to use Blogger for videoblogging, and it’s getting easier all the time as new tools become available. But one thing lacking is complete control over the appearance of your site. On that score, self-hosting with WordPress gives you much more flexibility.
Heath Parks, the Batman Geek himself, recently made the move from Blogger to WordPress. He ran into problems but persisted, solved them, and now he’s made a video to help anyone following in his footsteps. Check out Heath’s tutorial on Moving from Blogger to WordPress.
