The Planet Lisp archives are now fully online and automatically updating. There are still a few minor issues, but the major stuff is working. This required some invasive updates to how Planet Lisp works, so if you notice anything weird, please let me know.
Walter Higgins emailed me about his blog. It's not included on Planet Lisp because it doesn't occasionally discuss Common Lisp, but you should check out his elisp and scheme stuff if you're into that sort of thing.
