A standard feed icon

Feed Icons
Originally uploaded by travelinlibrarian.

The folks at FeedIcons.com are pushing the idea of a single, standard icon to indicate the presence of feeds. I like this idea. (If the Mozilla folks and the Microsoft folks can both agree on this icon, so can I.) I like this idea so much that I've already updated my link to this icon. But, and here's the funny part, does anyone but me find it odd that if you want updates from this site you have to submit an e-mail address? Wouldn't a feed but more appropriate?
