It is amazing that we waited this long to add what is fairly basic functionality. That said, I subscribe to the Ernest and Julio Gallo mantra of, "We will serve no wine until its time."
By that I mean, good interfaces that fit within the look, feel and workflow of the experience that is already plugged in take some time to bake.
I am not a believer of bolting on functionality just for the sake of adding a bullet point in a feature list.
Plus, obviously the basic engine of the service is working pretty well in terms of user feedback, core metrics and the like.
In any event, spend twelve seconds and see what's in channels. There is more functionality coming soon in this bucket but it's definitely serviceable and consistent with what came before it.
