Yahoo! Web Services news over Atom
Well, like a dork, I didn't actually realise that Yahoo! News already offered up the whole RSS feeds for news keywords thing when I started. However, the fun thing of course with the API that Yahoo! are offering is that it doesn't take a whole lot of time to create another script that dishes out the same thing in another 'rival' syndication format:

The syntax of the URL is almost identical to that of the RSS feed http://undercrank.com/yahoo/atom/news/«keywords» (the equivalent RSS version would be http://undercrank.com/yahoo/rss/news/«keywords». This is a slight change to the previous syntax posted, but the old format is still perfectly valid and won't break for those already using it.
As before, the feed validates nicely has good friendly HTTP caching facilities built in, as as a special bonus it conforms to the Tag URI recommendations pretty well too.
Use is made of the extended Author tags for each article, and support for multiple languages for each entry is available - although it appears that Yahoo! returns "en" as the language for everything, even, if it's not.
Finally, I'll post up the source once I'm convinced I'm doing everything the 'right' way.
