It's a horrible idea. Some people have totally lost all sense of privacy and dignity and respect for others (sorry if that sounds pompous).
As posters have said on other threads, it used to be bad enough before digital photography when parents could embarrass you by bringing out photos of you when you were little. But at least they were only shown to people that your parents knew and who were physically shown the actual photo.
I'd hate to be a child of an oversharing parent, growing up and knowing that there were photos of me on the internet that I might hate, but that any stranger could see.
