Andre Torrez wrote a blog post about creating a feeds.txt.

My friend Adam Mathes posted an idea called 'feeds.txt' back in August where he decided to publish his current subscriptions to a human readable text file.

Intrigued by the idea I was inspired to write my own generator. It runs nightly in cron and generates both a feeds.txt and a feeds.html file.

Turns out I still have a lot of cruft in my subscription list that I should clear out. Lots of blogs have disappeared into the ether. Shame that.
