I’ve become a huge fan of FriendFeed over the past couple of weeks (my FriendFeed page is here). Today I came across a great Greasemonkey script that allows you to filter your Friendfeed “river of news” by service. For example, you can cut down your news feed to only show Flickr photos, YouTube videos, last.fm entries, etc. I was so impressed by this script that I created a short screencast. You can get the Greasemonkey script at Internet Duct Tape.
