Here's a post on migrating to WordPress from blogger, which is what I'm leaning towards right now. Just as an FYI, there might be an "intermediate" step before the final URL change. A lot going on in RL right now so unfortunately, this hasn't been a priority and I'm feeling curiously unmotivated to figure out how to actually do all of the things I need to do to migrate the blog prior to May 1. So my current plan is just to back-up this one and then maybe use a different service for a couple of months until I figure out what the final solution is going to be. I just need time to think!
