The US Open has an RSS feed. Bing, as Dave Winer would say.
But the IBM folk who created the site should have another look. There’s the friendly orange XML icon on the home page, but don’t try copying the URL for your aggregator. It’s actually a link to a page that explains RSS, where there is a plain text URL to highlight and copy.
It’s a step forward, but it would have been so simple to do it better.
