I just never seen that except on my site. If I look at other sites with a RSS link using IE, it shows the RSS page when you click the subscription link.
Isn't the idea for someone to click the RSS link and then they can copy the Link from their browser address window to put in their RSS reader.
On my site, with IE, when you click the link, you get a popup asking if you want to save the document and it never shows what the RSS link is in the browser window so others can copy and subscribe.
Sorry, if I seem ignorant, but I thought that was the whole idea of putting a RSS Subscription Link on your site was so others could easily click the link to subscribe or to copy the link from the browser address window to put in their reader.
