Yep, 47 here, and no one except a couple of right-wing, anti-immigration activist "friends" seem to actively use Facebook anymore, out of hundreds. In fact, that's the main reason why I and many of my friends don't use it — it's around 90 % conspiracy theory, and hatred towards government and minorities now, and it's super tiresome. Everyone else is long gone.

In my opinion it's not the UI that is the problem; it's the decision they made to allow all nutcases with their nutjob theories to run rampant, in order to make a quick buck out of peoples' outrage.
