If I access:
https://www.facebook.com/clubambassadeur
I get a specific number for “were here”
But if I access:
http://graph.facebook.com/clubambassadeur
I get a different number listed under checkins.
Why are these two numbers different? I was assuming they represent the same thing.
Your first link’s “were here” equals check-ins + friends tagged in the check-ins that a place has got.
Your second link shows only check-ins, which is a sub-set of “were here” and doesn’t include tagged people.
