Recommend playlists with Flickr

Thanks to the wonderful world of web services and open APIs, Playlistr (for want of a better name) now lets you recommend and share playlists with your Flickr friends.
To try it out you'll need a Flickr account. Add me as an acquaintance, then once I've manually approved that (which could take a little while, sorry) go to the playlist page and Login. After authenticating, you should be taken to a new page with recommendations at the top. If you like, you can bookmark that page instead of the old one.
