I have had 3 acquaintances ‘drop off’ facebook in the last week. Basically they gave one ‘last’ post stating why and they were gone. I think a lot of people were willing to live with it through the election, but no one wants to spend the next four (or forty) years being insulted daily by people who don’t share your political views. It is just a drip for now, but if Facebook can’t come up with a better way for users to filter policital content or if a better service comes along it could turn into a full fledged waterfall of lost customers.
