My daughter wanted to join. (ToS say 13, though they didn't ask for a birthday). I created my own account to check it out, and did so with an email address (the review says only Twitter/Facebook; that no longer applies). Then the site asked me to go through and select 5 pictures that interested me. There were lots of pics that would be fine for kids, but also references to gay porn and sex, lots of cursing, references to alcohol being a savior of sorts/being drunk, scantily clad women/men, and negative messages. I have no problem with adults seeing this stuff, but it made me think that my daughter shouldn't have access. She wants it for crafts and fashion, and I could just select the beginning interests for her when she registers, but if the stuff she's shown when she opens the site is inappropriate (as I saw when I opened the home page, and I chose nature pics and science content), I worry about her seeing it. My original concern was the social aspect, but I think the site has too much adult-oriented material for most young adolescents. I'm going to play with the site more, but so far I'm not ready to give it a green light.
