Too young for YouTube?

Recently, the use of young children on sites like YouTube has raised concerns of appropriateness. It seems that where parents used to post videos of their children merely for family members on YouTube, now parents are exploiting their children for instant internet fame.
 While television programs like "Kids Say the Darndest Things" and "America's Funniest Home Videos" have been a part of the American entertainment culture for decades, it is only recently that parents have had direct access to making their children international stars.

Even if the threat of online predatory pedophilia could be ignored (it can't), what happens when these kids reach puberty? Or High School?

Did anybody else have a mother that showed pictures of them in the bathtub to their high school girlfriend? I did, and it was embarrassing. However, it helped me learn what girls to bring home to mom and which ones would not be able to handle her. Mostly, I learned not to bring any girls home to mom when she had access to family photo albums.

But what if any student at my high school had direct access to family videos of me as a kid? How could I ever quash that? I wouldn't be able to, and fortunately my parents never posted flyers of me in the tub around my school.

Parents that share too much of their child's life online are endangering themselves as well. Just ask the balloon boy's parents. The threat becomes parents exploiting their children for their own fame, and then having it blow up in their face.

Or worse, it could create a need within the child to forever feel the love they gained while on YouTube. Maybe we shouldn't be concerned though. I mean, surely these kids are growing up in well-adjusted environments, right? Right?
