This is my first Branch topic and I already love the service - it's intuitive, it's innovative, and it's organic. However, despite the fact that you can embed Branch widgets on other pages, there doesn't seem to be any way to subscribe to a Branch using RSS (though you can subscribe via email)
Am I mistaken about that? If not then Branch is ultimately no more open than Facebook or Twitter. Branch's mission statement is about fostering conversation in a new way; but doing so by the old way of a closed content silo doesn't really achieve that goal in a global, broad sense.
At a bare minimum, Branch topics should be RSS-compatible. This would allow users to back-up their Branches, to create new functionalities (using tools such as IFTTT).
