I've been on FB for YEARS. (Since before it was open to the public, and when you lost your school email, you lost your access).
I'm also an (amateur) photographer. I shoot about 25,000 pictures each year. I preserve them on harddrives. As in 2 external harddrives. One that's in my house, and one that's in a safe deposit box. I also have about 5000 photos (my favorites) that I backup in an online storage company.
I DO NOT like to post my photos on FB. Sure, I post a few (maybe 20 or 30), but that's it. I also DO NOT like to have others post photos of me or my family on FB. I can deal (sometimes) when it's just me... but not when it's my kiddo. And that's my choice. I don't want pictures of my son on a public forum. Period.
I certainly understand FB. I certainly understand photography. But I am also my son's mother. And I have the right to limit his exposure online or to the public. This is not a "new" concept. (AKA this is why consent forms are needed for prof photographers from the news, magazines, even art photographers. Even models have to sign their consent to have their image used publicly, and child models have to have their parent's consent).
It is a right to privacy issue. As in we each have that right, as well as the right to have our desires for privacy be respected. As someone whose husband is somewhat famous... I even understand the idea of a "public" life. I don't want one, and never have. (Fortunately he's in music, not film). I don't want strangers oogling my or my son's life. Which is what those 360 people who are not in your circle of friends ARE to your friends, regardless of how well you know them. Strangers, given an all access pass to anything you post.
Respect your friends' wishes for privacy. Not doing so is exactly like realizing that FB has lifted all of your privacy settings. It's an invasion. You get the choice to set your own privacy levels, give your friends the respect to allow them to do the same in their own lives.

"Maybe if you haven't lost important people in your life you don't treasure memories as much as those of us who do."
Honey... that's an unkind & unrealistic statement to make. I can't count the number of people I've lost, and in the past 8 years my son has been to at least one wake per year. Posting photographs on facebook is not the definition of treasuring memories. Much less does it mean that if we don't post photos that we haven't lost people we love and care for... or that we love those people any less.
