There’s a great new interface for subscribing to feeds. The process of adding a new feed has been streamlined by giving you the ability to rename and tag feeds while subscribing.
Before, subscribing, renaming and tagging were separate operations. You had to click around a lot to get your new feed in the right place with the right name.
Also, you can now see a favicon and the feed URL for what you are about to subscribe to. And the whole thing is easy to navigate using just the keyboard.
