There is nothing wrong with looking. I personally don't bother with it, but I suppose I see no harm in checking out who else is applying to the same school? As you said, they can't do anything with the information so who cares if they look?
Concerned about what exactly? Maybe it's me but, with all the stuff I have going on, the last thing I would have time to do is stalk a random person.
Your crazy/stalker mileage may vary though, I suppose.
Just want to extend a good luck to everyone! I'm still waiting on two schools, so I know how nerve wracking this can be!
Just to add the schools I heard from unofficially and otherwise: USC, OSU, UNCW, and LSU.
