RSS and atom feeds is now available for blogs and statuses. The feeds links are located below the blog stats on the blog page and in the Status box header, to the right, on the public profile page.
You can subscribe to blogs and statuses in Google Reader by simply pasting in a blog or profile URL into the subscribe box. Google automagically figures out the location of the feed.
Please note that the profile and blog must be viewable by everyone to be accessible by Google or other news reader. You will be able to subscribe to restricted blogs and profiles if you are logged in and use in-browser functionally such as Fitefox's live bookmarks.
Let me know how this feature can be improved.
