I dont know; they may well have been on the ads and moderation side. And they did add the hangouts/voice calls stuff, but that may have been an acquisition, I'm not sure.

And to add: the new features are take or leave it. you're right, who cares about new features on _twitter_, it was ossified already.

Becoming the worst place on earth is a far weightier outcome of the aquisition and firings.
