I haven't used Google sites too much since I have so much webspace under my namesake domain, but I found this interesting. You can use google sites APIs to export, delete content (eeks, use with caution, I'd say), and more. Very cool -- although I'd love to be able to (export/import) dump the CONTENT of a google site directly into a spreadsheet or google docs (hint, google!) without having to do any extra work. Now that would be handy and I might actually use google sites more.
