FeedWordPress

FeedWordPress is an open-source Atom/RSS aggregator for the WordPress blog publishing platform. You set up feeds that you choose, and FeedWordPress syndicates posts from those sources into your WordPress posts table, where they can be displayed by your WordPress templates like any other post — but with additional meta-data, so that your templates can properly attribute the post to the source it came from.

FeedWordPress was originally developed because I needed a more flexible replacement for Planet to use at some aggregator sites that I administered. You can use FeedWordPress to create aggregator sites that bring together posts from many different sources, using the WordPress templating engine to display posts from all around the web. Or you can use it to bring together activity from your blogs, social networks and other online services, into a Lifestream with all your online activity in one place.
