There is a new feature I just found out about: Facebook publicizes when I've viewed a post on a group page.
I'm not sure whether this is just for group pages or on friends either, but I'd like to be able to turn it off.
How can I do this?
Apparently you can't. it's probably possible for group admins only, however, you can leave the group and people will no longer know when you've seen a group post, even if you saw it before you left the group.
