Update 2007-11-21: FeedWordPress 0.8 is now out of date. You can download the latest release — 0.991 at the time of this writing — from the project homepage.
FeedWordPress is an Atom/RSS aggregator plugin for  1.5. You give it a list of websites with Atom or RSS newsfeeds and it will syndicate posts from them into your WordPress weblog. It uses  to parse the feeds and some simple transformations to store the data as a post in the WordPress database. It’s a classic case of “itch-scratch ware”–I wrote it specifically because I needed something more flexible than  to run Blogs. But Blogs isn’t the only aggregator site in the world (let alone the only *potential* one), and I’m making the code public in the hopes that y’all might find it useful and pleasant to work with too.
One of the things you’ve got to do in life is keep track of the people that you owe. FeedWordPress is free software, which makes use of code derived from more than one other free software project. The core aggregation code is adapted from an experimental PHP script (wp-rss-aggregate.php) by Elliot McCrae(http://www.laughingmeme.org/); auxiliary modules are adapted from a URL class by Minoukadeh(http://www.keyvan.net/), and the Feed Finder(http://diveintomark.org/projects/feed_finder/) by Pilgrim(http://diveintomark.org/). FeedWordPress might have been possible without their help, but it sure would have been more of a pain in the ass. Thanks, everyone, and here’s to free software!
