We all make choices about what is right for us. You're comfortable with your approach, and certainly entitled to your own opinion. Me, on the other hand, will support any parent's decision to limit specific information about their children on any public forum.
Frankly, until recently, I never gave it too much thought before (I don't have kids). I've enjoyed all the funny stories about people's kids, photos, etc, posted on here. But, it is a new world now, in the sense that the internet opens the door to both good and bad experiences. (When you and I were growing up, the internet was there, but hadn't entered the "mainstream" American life.) To me, in today's world, I can understand why many parents are taking a more current review of precautions, for their kids. I'm sure the precautions vary from parent to parent, and all do what they think is best in their own situation.
