So I’ve just spent a half hour messing about with Yahoo! Pipes, which is a neat tool for creating RSS feeds from disparate sources, and have ended up with a tidyish RSS feed of almost all of the sites I have linked from this blog.

I hope someone finds it useful!
(Yahoo has unfortunately since closed down this service)
