I see an execution gap here, though. My blog is, what, 2600 pages? I'm obviously not going to build that XML file manually (with one node for each page). Google does provide a Sitemap Generator, but it's Python code meant to be run on my web server. My Python skills are nil, so that route isn't viable for me either. I expect that there's a good many 'webmasters' (as in, people who design and run websites) who don't know Python from perl.
Given the CC license, though, maybe somebody will grab the code and build an idiot-proof solution for the Sitemap Generator.
