Today’s fun task is to go through all the Yahoo! properties and catalog which properties supply RSS feeds. There are a buttload of them. (I’ll publish my results on the developer Web site presently.)
I unearthed a fun one on the HotJobs site. If you do any kind of search on HotJobs, the search results are displayed along with an RSS link (which you can optionally add to My Yahoo with a single click). F’rinstance, this link is an RSS feeds that contains jobs at Yahoo itself, but you can hack up the URL to work for any keyword.
