I have set up this blog with its own domain name: bananagrammer.com. It's still hosted on Blogspot for now, so the old URLs should still all work. Specifically, if you use an URL that looks like bananagrammer.blogspot.com, Blogger will automatically forward it to www.bananagrammer.com.
If you are subscribed to the feed, you might have to change the feed URL. Or you can just delete the old one and resubscribe through the new feed.
For the moment, everything else is the same as it was, but in the future, I will have the flexibility to try out things that do not fit neatly into a blog post.
