I only spent 15 minutes at FeedDigest “Making Your Feeds Fabulous” but its got a whole lot of “oompf” potential if you are trying to do more with using multiple feed sources. More or less, you create a “digest” that you can then mix in a few RSS feeds, and Feed Digest provides a whole raft of ways you can re-use the mixed up content.

Somebody up north may want to crank up their aggressiveness 😉 Inside joke.

Not feeling very creative, I whopped up a CogDogBlogest a mix of my WordPress blog feed, my del.icio.us feed, and my flickr feed. Ho hum. I get a RSS URL:
http://app.feeddigest.com/digest3/VGE7KGLMJ8.rss

But there are ways to customize the output with some pre-made and editable templates… and you can then resyndicate to your own sites using JavaScript, PHP, and some other tools.
