Collaborate with Google Docs

OK, this is really cool and revolutionary. Google has released their online word processor aka writley. The new release, known as Google Docs is integrated with Google's online spreadsheet. With docs and spreadsheets, you can invite others to collaborate with you on a project and keep the project private. Each user logs in with their own Google account. Revisions are tracked, so it is easy to revert to previous versions. You can also publish your work to a unique url so that it can be viewed by anyone online, but not changed. The really cool thing is that you can track all changes via rss feed.
