Subscribe to any page with Google Reader. No feed? No problem.
To take advantage of this new feature, just go to "add a subscription" in Google Reader, and put in the URL of the site you want to subscribe to. You'll see a notification that the site has no feed, and the option to subscribe anyway. It works well on the homepages of large companies, like Microsoft and Apple, that update with product launches, but don't use RSS to share that information.
If you're looking for a way to subscribe to changes in a web site using a feed reader that's not Google Reader, you might want to check out page2rss, a web site that monitors any page for changes and creates and RSS feed that you can subscribe to in any reader.
