Merging multiple RSS Feeds into one

If you'd rather not rely on an external service, it's super-easy to use SimplePie ( http://simplepie.org/ ) to merge feeds and, if you'd like, output another feed: http://www.webmaster-source.com/2007/08/06/merging-rss-feeds...

(Not the best tutorial, we should have one on our wiki. Disclosure: I'm the SimplePie lead maintainer.)

I built and sold a company that focused almost entirely on this one task several years back :-) It's still going though I can't personally vouch for it as I don't use it any more. Nonetheless: http://feed.informer.com/

I did exactly this to make a poor man's blog planet a few years ago. The only problem is that you get a rather messy looking system of pipes and modules as you add more and more feeds.

You could also use our WIP http://thirsst.com -- but we disabled the feed bundles for new users. Ping me at ryan@grow20.com if you care.
