To answer the previous question about why we don't put photos of our children online, I have several reasons
1 Our children will have control over how their image is 'projected' to the world. The vast majority of us grew up not having our parents make this decision for us, I want my children to have the same power. What if they want privacy for some reason, or don't agree with how you've 'presented' them?
2 For their privacy/safety. People don't seem to realise how much information they put about themselves and their children online. It's so easy to work out schools, routines etc for anyone malicious.
3 I have a specific family member i am NC with, who is dangerous. Refer back to point 2. Even if there's no one in your life like that NOW anything previously posted is a mine of information
4 Once you've posted this stuff it's out there. It doesn't matter how well you've 'locked down' your privacy settings.
The arguments for posting are what, people I've not seen in 20 years get to see photos of my children? Anyone I have a relationship with/am in contact with gets updates on our lives and photos in a natural way and if they havent that's fine because we're obviously not close enough anymore they 'need' to know this stuff
The caveat to all of this is that I don't post myself, although I do 'lurk'. So all of this comes from a context of me not sharing the same aspects of my own life.
