The chatbox on the right is outrageous. "The other person is typing" should never be allowed to have this huge and distracting of an animation.
I picture myself typing this on my phone, letting it rest on the desk unlocked while continuing to read HN, but finding myself constantly disturbed by these bouncing waterdrops in my peripheral vision.
I won't argue against read receipts and typing notifications in general as far as UX goes (I understand the privacy problems, but that's another thing). It's a very basic equivalent of body language for text chat.
