As you've no doubt noticed if you've been using it, the Geoff Gannon RSS feed I posted a while ago no longer works. The feed now provides all of Gurufocus' most recent articles rather than just Geoff's. I think the issue is that Gurufocus changed their format for the URL address of writer articles, so that the original URL now points to all of their recent articles.
Fortunately, Gurufocus now has a link below the author picture by each article that links directly to an RSS feed for the author's articles. This feed does the same thing as mine used to, but without the occasional errors, so rather than go fix my feed, I'm going to just provide a link to the new feed. Geoff's author RSS feed can be found at http://www.gurufocus.com/rss_2.php?author=Geoff+Gannon
