As a current college student that operates in a community where I see a number of my fellow classmates using reddit online during class I can say that they would not pay for directly for the service. These days there are too many supplements to Reddit that entertain me just as much if not more.

Although I do believe that Reddit is a very established and well liked website that would still see success if they charged a subscription fee, just not on the same scale of popularity that they currently do.
