I have begun my migration to Blogsphere. Not being a Domino web developer I'm struggling mightily, but it is coming along. I'll be sure to post how I did the migration from Blogspot / Blogger to Blogsphere. It's not going to be easy.
Here is a preview of what I have so far: http://www.cubert.net/. Not much so far. Watch this space for updates, or check the new URL if you want to watch me struggle. :-)
