I dunno, I think the “protocol” vs “social internet” distinction is still a bit over people’s heads if all they really know about the internet is Facebook and Instagram.
Maybe the best way to describe it is as a new social network (already technically incorrect) that people are excited about because it works differently from any other social network in a way that puts more control over what you see in your own hands, and lets any application developer make new apps that can show different kinds of content on the network in cool new ways.
Either that or #penisbutter
