Do you prefer Facebook or Instagram?

i have facebook and instagram, but cant figure out instagram, so pretty much only use facebook. Now i feel old too.
I wont post on facebook either, as i have a problem with the fact people need to tell everyone else every single aspect of their lives.

And dont get me started on the facebook posts that people make for a reaction or attention. You know the ones.. the ones that moan about something but dont tell you what it is, as they just want you to ask.. "aww whats up?"
