Edit: I've checked it, thanks, it seems good, but I'm wary of adding another app to my list. As long as I can add photos and my closest family/friends can see them, FB is enough for me. :)
FWIW, I finally signed up for instagram a few months back - mostly to post artwork. I had hesitated: I don't have facebook on my phone, after all, and figured facebook was enough.
Much to my surprise, It seems to be a much better platform for artwork and photography (most of my followers are posting the same, so generally interesting to go through as well). It will also post to facebook from the instagram app.
