They no longer require Live Bookmarks to be the one place to store subscriptions. Firefox allows you to set which program should run to subscribe to the feed. Now, it pops open IE7 and I have to click Subscribe there so it isn’t seamless but it makes a good argument for me to jump back to Firefox; merely to combat my “IE7 woes”:http://www.johncblandii.com/2007/10/ie7pro-are-you-killing-ie.html.
PS. If you know how to use Firefox to subscribe to Vista feeds, seamlessly, I’d greatly appreciate some tips. 🙂
