Michael Sippey has figured out a clever way to use feedburner to intersperse his flickr photos into his rss feed:

If you subscribe to my feed, you may have noticed the today's appearance of a few photos. These are the result of a very interesting partnership between Flickr and Feedburner. Feedburner now supports Flickr photo feed splicing: all I had to do was give Feedburner my Flickr username, and since Flickr outputs my public photos in Atom and several flavors of RSS, Feedburner grabs it, and merges it into my blog feed based on pubdate. Chocolate, meet peanut butter.

Why is this huge? Sippey says:

As I ranted about in a post on the Supernova conference blog, if you're out to use RSS to replace email, you've got a long road ahead of you. But if you can use it to start to change the way that "publishers" and "subscribers" produce, distribute and consume information, then you're on to something.

Is the future of social networking in syndication? 

Marc Canter's soapbox says so. 

Update: Oops! Looks like Harold Check beat me to this one.
Update II: Oops II! Looks like this is a formal-ish partnership between flickr and feedburner.
