Ask HN: Is there anything interesting about social productivity?

We are working on a simple solution to work-life balance in college. Students sign up with their current schedules.

They are reminded of academic obligations (tests, assignments) via a shared class calendar. Students can also create social plans like ("Coffee with Tim and Sarah") with friends. They can check in for either of these so other students can see them and possibly join.

We've got great feedback. But I'm wondering, what's a good way to make "social productivity" seem more interesting?
