This utterly rocks, and I can’t believe I didn’t go looking for something like it before: MagpieRSS lets you show RSS headlines on a PHP page. I’m using it on my old toxiccustard.com page to show the latest headlines from my diary and the site’s News and Guide to Australia pages (which all run WordPress). It includes caching so you won’t burn up your (or anybody else’s) bandwidth by grabbing the feed continually.
