Our facebook group member count is wrong at the moment. Facebook changed API. Fix will be deployed shortly. http://20ft.org/fbgrpsfail
Facebook changed their API. That is why the TwentyFeet measures for the number of facbook group members (only groups, not pages, apps and profiles) are wrong the moment. If you create a new account, nothing will be counted for group members at the moment. If you already track a group, the same amount will becounted, no matter what really happens on facebook. The problem is already fixed. But we will not deploy it live before the next two weeks, as we prepare some core changes on the platform.
Thanks for your understanding. Please bear with us.
