Facebook is for Old Folks

Actual conversation in one of my classes Friday:

Me [trying to sound hip while making a point]: So, different genres, different kinds of texts, have different expectations of the reader.  You know this already.  You read your financial aid award letter differently than you read your Facebook feed, I'm sure.  Uh, wait.  Are you guys even on Facebook, or is that just for the old folks now?

Them: Old folks, man.  That's definitely old folks.

Me: So, what are you guys on?

Them: Twitter!

Me: Oh.  Okay.  Twitter.  Yeah, okay.

Them: And, yo, Instagram.

Me: Wait, what?  I thought Instagram was old folksville!  Like, people sharing baby pictures for the grandparents and, you know, pictures of their food at restaurants.

Them: Naw, we all on Instagram.

Me: So, what do you . . . like . . .
[massive giggling ensues]

Me: Uh, never mind.  Don't tell me.
