Just realized that when I was working on the RSS feed for the Newshound that I made a comment about the "little orange box" in the lower right column indicating that an RSS feed was available.
Thanks to an e-mail from a friend of mine today, I realize that the little orange box is not a feature of Internet Explorer. I so rarely use IE these days that I had forgotten to check it. Stupid really, since more than 90% of the Newshound users are still using IE.
Anyway, the orange box is a feature of Firefox that allows you to use live bookmarks. I see it as a sign that a site has an RSS feed, but I'm probably wrong to so closely associate the two.
