Slick WordPress plugin that makes posts from RSS feed items. (I'm using it to auto-post links to Tumble, including this one.)

"Feed Rinse is an easy to use tool that lets you automatically filter out syndicated content that you aren't interested in. It's like a spam filter for your RSS subscriptions."

This is essentially a hosted weblogging app that outputs only a RSS feed, no website. Interesting. (I did the same with my old podcast, using XSLT to magic up a web page for anyone who happened upon the feed.)

Not another one!

Exhaustive overview (I'm writing a non-geeky introduction to podcasting today, God help me)

The latest posts from Flickr and del.icio.us tagged with 'glasgow' on a page of their own. Folksonomicalaggregationtastic.

This looks to be the best way to syndicate RSS feeds on a web page with the minimum of fuss. Easily customised, styling with CSS. Free.

Converts OPML to HTML. Obviously.
