Interestingly enough a guy I worked with here, was not considered by a med school because they tried to look him up on fb and saw it was completely baren and locked down. They looked at other social networking sites as well and saw the same thing. The guy was told that he wasn't going to be considered because they wanted applicants to have some kind of social like outside of worrying about whether or not they could get into med school.
This pissed they guy I work owith off, I laughed. Turns out this conversation came out after a few drinks.
