I have some relatives that are ex-cons. Should I post their pictures here?
While hilarious, they may not appreciate that.
In that spirit I will point out that for a variety of reasons, some mundane and very boring, people do not like their pictures or happenings put out on the internet. So to a degree, what happens at GenCon, should stay at GenCon.
For Example:
Some authors like to maintain their anonymity, so they do not like pictures distributed.
Some guys are married with children and don't want pictures of them staring at booth babes released.
Some people have professional jobs and do not want their drunken exploits to get back to their boss.
