The Think System
I don't know where the picture originated, but for a site like The Big Lead to get their hands on it, they either took it (very doubtful) or were sent it by someone who saw it somewhere (very likely). This means some nitwit took a picture of football players at a party and, for whatever reason, decided to share them.
Now, obviously I have some experience running a website*, so I have a reasonably good idea what led to the posting. Someone had football players at his party and wanted to show his friends at home he was hanging out with them. One of the players' friends wanted to make sure everyone saw the goofy "uniforms" they were wearing. I'd like to think it wasn't because someone wanted to get them into trouble. But any or all could have been the cause.
Unfortunately, as so many in their situation do, the poster didn't think it through and realize what posting something on the Internet does.
So often, people on message boards or social websites or the Internet in general get caught up in the individual conversations or exchanges that take place through the electronic medium and forget the wider audience involved. If you're sending an email to your buddy, Joe, it never occurs to you other people might see it if Joe decides to forward it. If you're participating in a message board thread, you're focused on your discussion with a couple of other posters, not realizing thousands of other people who aren't posting are reading it (and maybe copying it into emails and sending it to even more people). When you put something on MySpace or FaceBook (or even LinkedIn), it goes beyond your 10 friends on the cheerleading squad, and may end up with teachers or parents before it's done.
It happens over and over (as detailed by The Fire). This isn't even the first Notre Dame-related example ... I recall an email written by a recruit's dad that ended up forwarded to thousands of people. In the email, he shared some details about his son's visit to ND, including some exchanges with coaches that were meant to be private. Both the dad and the kid ended up very embarrassed over the entire thing. But again, it wasn't thought through.
I suppose what bothers me the most about it is the response in these situations is never, "Gee, maybe I should think before I post something online", but rather, "Stop harshing our buzz, man, I can post what I want." You should never blame other people because you don't think. Remember the Miranda warning: Anything you say can and will be used against you. Would you walk into your parents' bedrooms and tell them, "Wow, you wouldn't believe how many beers I had last night" as a senior in high school? Would you tell your wife about the hot girl you were flirting with at a bar when you were away on a business trip? Only if you're an idiot. But if you post it online, you're as good as doing that. Idiot.
As I've said many times about NDNation, when you open something up to the public, the public tends to show up and you shouldn't blame them when they do. Unless the medium you're participating in is somehow restricted, like a premium content website, what's said to one is being said to all. To expect people not to read your publicly-available profile or site or post because you have a right to privacy is at best self-contradictory and at worst really really stupid.
So next time you're going to hit the "post message" or "upload photo" buttons, think for a minute: Who is the absolute last person I'd want to see this picture, and what are the chances he or she has Internet access? Then think a little more.
