Google Reader has added a feature that recommends feeds for you. Recommendations for new feeds are generated by comparing your interests with the feeds of users similar to you as well as by looking at your web history. A help page explains the process…

The “Top Recommendations” section lists a few feeds you might be interested in, but aren’t subscribed to yet. You can get more recommendations by clicking the View all link next to those recommendations, or by clicking the Discover link in the sidebar.

You can preview a feed in Reader before making a decision to subscribe or not; just click on the feed in the list of recommendations. There’s also some extra information about the number of subscribers to the feed and approximate posts per week. If you find a feed you like, just click the Subscribe button to add it to your reading list. If you’ve decided you’re not interested in one of the feeds, just click No thanks to take it off your recommendations list.

Your recommendations list is automatically generated

Here’s a screen shot of what this looks like in my reader. Though it’s not very controversial since all of the data is anonymous, it would be great to see Google give you an opt-out choice since some people may not want to share their reading habits with the world - even anonymously.
