It's great that young people are diversifying in this way, but isn't it a little apples to oranges? You don't use Facebook to send disappearing images to each other, you don't use Instagram to plan events or remind you of birthdays, and you don't use Snapchat to share pictures of your cat with followers around the world. They're very different things, yet they are all lumped into the category "social network" because you can make connections with people. By that standard, practically any online service or platform these days is a social network!<p>Still, it's very significant that Facebook is not the go-to thing for lots of online connective tasks (even if they do own Instagram). People don't want all their interactions to be on one platform for the same reason no one puts all their eggs in the same basket, and in addition, there are nicer baskets out there to try out!
