I read through your site, and I'd like to congratulate you on what I think is an excellent job. I noticed a few typos and some stylistic things that could be worked on, but these are the only major caveats I have:
1) In pointing out the parts of the books in the first section, you're kind of giving girls guidelines yourself; however, because your intended audience is not people who are already pro-ana/pro-mia, and because these books are so widely known in those communities anyway, I don't think this is realistically too much of a concern. However, I think you might add a warning at the beginning of that page that those accounts could be triggering for some people dealing with eating disorders, and perhaps some hotline/resource information for people with ED who find your page.
2) I know that you only used folks' screen names in your quotes from users section, but do you have permission from the site(s) you took the quotes from? They may belong to the administrators of the site. It's always good to get permission and keep things squared away.
Apart from that, it looks like you did a very good job. I was not familiar with Tracey Gold's book; I'll have to check it out.
I hope this helps!
