You don't want the old Instagram

Bogost argues that Facebook should be more like how Google+ was originally conceived, back in 2011: built for intimate, small-group relationships.

tweets on Twitter and photos on Instagram are public by default, and anyone can follow anyone. The default medium, though, is fundamentally different: Twitter has photos and videos, but the heart of the service is text (and links). Instagram, on the other hand, is nothing but photos and video (and link in bio).
