In reply to Alyson:
I post pictures of our wee lad on facebook in the context of limiting privacy settings to friends only. Grandparents have gotten themselves online, so we use it as a way to share pictures, and at the moment its working the other way around as the sprog is in North Uist with his grand parents, and we can see what he's been up to. We don't allow tagging, and certainly wouldn't allow a FB account to be set up as some people do. Our nursery also use a facebook account to provide pictures to us of what Angus has been up to.. ..again, under strict privacy settings. I feel pretty relaxed about pictures of him being online... ...and indeed feel it threatens his privacy less than the large dressing screen at my parents house which has been stuck with pictures of me and my brothers and sister, nude playing in the garden, nude in the bath, nude with paints, and pictures as we have grown up, rock climbing, up the top of mountains etc. All of these are on show, as this screen has sat in the dining room for the last 20yrs or so... ...no preservation of privacy there. Then again, while I'm a pretty private person, my family is in general very unprivate.
The only argument I can give is that we get much pleasure showing photos to our friends and seeing their comments.. ..often as the source of a joke or humour (like the lookalike I posted of our lad with his little hair in the centre going forward, playing his uke singing at the top of his voice, placed alongside a picture of Mark Knopfler doing pretty much the same).
