very interesting - sadly the version I have tried publishes multiple copies of rss feeds, so I had to disable

more info please....
Very early days yet. At the moment all it does is poll feeds in turn (currently it's configured to look at about a score of them, mostly British and US quality newspapers and major news agencies such as Reuters, AP and AFP), filter them according to a keyword, convert any HTML content to text, format in UBB and post.
I plan to add code to make it remember what it's posted and avoid reposting. There would still be a duplication problem if, say, a newspaper source republished an AP story on its own feed. I'll deal that when I come to it.
It's written in
Chicken Scheme, a form of Lisp, and makes extensive use of
SXML. I'm running it under Ubuntu but it should compile and run okay on any modern operating system.
