"Everyone is already on it and it has a notification system that people check b/c it's how they find out about college parties"

In that era I recall several US universities career offices gave students the blanket advice that not having a facebook page would raise an employer's eyebrows.

"(I suggested Reddit and he acknowledged that would probably be one place where you at least knew students from the school might be there and were interested.)"

My impression of the college kids I deal with is that they now all use LinkedIn. (I think? It feels weird even saying that.)
