Google Reader is a cool way to use RSS feeds to more quickly scan through content on sites that you regularly visit. You can also quickly share the articles that you think are interesting and others can subscribe to an RSS feed of your shared items. Think of it as a pull distribution method for all the web articles that you sort of want to email links to everyone about, but know that it'd be irritating if you did. Over there on the right of my blog page you can see some of the articles that I've recently shared.
Let me know if you start using this, I'd like to subscribe to the shared article feeds of any friends and family that use this.
