As someone who attended before and after the change: there was certainly no immediate effect. The consensus at the time (at least amongst my little circle of friends) was that adopting the Common App was an obviously short-sighted metrics play.

It's definitely been superficially good for my social life, but I remain very sorry that the Uncommon App is no longer around. It played a nontrivial role in my decision to apply in the first place.
