I love Reddit's interface, I'd like to use Reddit to access the feeds that I normally use Google Reader for. How can I treat arbitrary RSS feeds, such as BBC News and ycombinator, like subreddits?

I think you can create your own subreddit and automatically post everything from a rss to that subreddit.
