If you’ve left a comment here in the last two days only to see it disappear later, could you email me at AlyssaObserves [at] gmail [dot] com with the following info:
1) Which post it was.
2) Whether it was a reply to another comment or a stand-alone comment?
I’m incredibly sorry about this. And please know we’re working as hard as we can, internally and with Facebook, to get this fixed.
