Favorites are the best way to discover great photos. If you know a few Flickr users that have great favorites, it is pretty uneasy to check them on a daily (or weekly at least) basis. Flickr provides feeds for a lot of things, but none for the favorites. I don't know why Flickr doesn't provide such feeds for that yet, but I have made it available from outside thanks to the Flickr API.

This screenshot is taken from Tom McFarlane's favorites page, with my userscript running in Firefox thanks to the Greasemonkey extension:

Basicaly, it adds a link to a RSS feed for these favorites, which allows me to subscribe and be informed when Tom faves any new photo. The picture shows the feed icon with the text next to it, saying "Feed - Subscribe to Tom McFarlane's favorite photos on Flickr"... These icon and text are added dynamically by my greasemonkey script, which creates a link to a RSS feed I will provide with calls to the Flickr API.
