Google Sites just received a minor makeover. The navigation bar can now be set up as a tree structure and the new editor looks very similar to Google Docs (other minor changes are here). I'm so happy about the addition of this new editor, it creates a level of consistency across the Google Apps suite which is much needed since desktop office suites have been offering this for years. More changes to site navigation will happen in the next few months, along with integration of adsense and collaboration tools. It's nice to see Google adding these features to sites. I've been using it for the past 8 months and it's super at meeting my needs as an educator. My favorite aspect is the integration of Google Docs; documents can be embedded in a site and styled with just a few clicks. This indeed shows the power of cloud computing.
