I have been using Yahoo! Alerts to alert me to changes in my custom RSS feeds, crawled from CalTrans, for changes in the status of Interstate 80 over the Sierra. I noticed today that although my RSS feed has picked up the recent changes, Yahoo! Alerts doesn’t seem to be crawling it, and their view of it is 5 days stale at this point. There is no “refresh” button on Yahoo! Alerts, but I can see their list of items matches up with 5 days ago in my feed. I have it set to send me changes “as they happen”, since I need to know the road conditions to drive back and forth to Reno. Anything else is kind of worthless. What’s up with that?
