I email pictures of our daughter to family, but I don't have a facebook account or host them on my webpage or anything. I don't have the same reaction as some of you though, I'm not appalled when others want to show pics of their kids online.
People do want to see them though (at least women). Every woman I know and see at work is constantly asking me if I have any new pictures, expecting me to carry a whole album in my pocket. So I understand why people post them online. I wouldn't look like a dick for not carrying tons of pics everywhere if I had someplace for people to go see the pics on their own time.
