Site44 is a free webapp that hooks up with your Dropbox account and lets you create multiple web sites inside your Dropbox account for the world to see. Create the page with their site builder, and then manage and edit the site locally—your changes will always sync to the web.

The video above does a great job of walking you through how Site44 works, but the process is simple. Connect the app to your Dropbox account, pick a .site44.com domain for your site (or use a custom domain you already own,) and the service will drop a folder in your Dropbox folder that represents that site. From there, you can edit and manage the site on your own computer, including uploading images, creating a directory structure, adding CSS for your page to use, other documents linked on your site, and more.
