Summary
After a lot of (occasional) research and experimentation, I've finally found a new home for this blog, using Jekyll to create a static site served by Github pages.
This move is a big improvement and I think it frees me up to blog more. I like the look, and it works well on handhelds, too. There's a detailed post on the new site describing everything I did to get it up and going.
Thanks so much to Bill for creating and maintaining the Artima blogging site, which filled an important need when he built it.
