Official Google Blog: Google Sites now open to everyone

"A few months ago we launched Google Sites exclusively as part of Google Apps for companies and organizations that wanted to use the service on their own domains. Now we've made it easy for anyone to set up a website to share all types of information -- team projects, company intranets, community groups, classrooms, clubs, family updates, you name it -- in one place, for a few people, a group or the world. You can securely host your own website at http://sites.google.com/[your-website] and add as many pages as you like for free."
