The new RSS features are now online! You can subscribe to feeds for all notes from a book, all notes from a user, or all notes from a user on a particular book. The respective RSS links are at the bottom of the notes and user pages.

To subscribe to notes from a user on a particular book, first view that user's book notes (click on that user's name or avatar, then click on a book from their page). The feed link will change to just that user's notes on that book.

RSS is pretty powerful and pervasive these days. There are lots of things you can do with them. Here are some ideas:

1. Add your note feed to your blog roll.

This lets you easily incorporate your reading notes into your blog, and makes it easy for your friends to follow along with what you are reading. I just added my notes feed on to the blogroll on this blog.

2. Follow along with someone's reading

See a reader with similar interests? Subscribe to his or her feed to see what they are reading next. If you don't already have an RSS reader, check out bloglines. It's fully online and one of the best.

3. Stay up to date with notes on a book

Subscribe to book feeds to see what other people are noting on that book.

4. Add RSS content to your blog or website.

There are several widgets out there such as this one from widgetbox, which works well with Blogger and other blogs plus Facebook and MySpace.

Well, no doubt all of you can come up even better and more fun things to do with the RSS feeds. Leave a comment or feedback and let me know what you think.

For the more technically inclined, Scribilus's RSS feeds conform to the RSS 2.0 format.
