Consider this too, even if you've made the decision to be public about it, it can still come back in ways you might not be ready for. Like, I run a twitter account basically for my disabilities and some little stuff, and I've posted the occasional picture or two on it as one is wont to do. Personally, I'm pretty open about this stuff, and it was meant to be public and didn't have my face in it, but it was up nonetheless.
In a completely unrelated context in another internet forum I had gotten into a political discussion and made a guy angry enough to go off site and look for things on me, he found a picture from it and posted it on the site thinking he was going to use it to insult and "get one over" on me. I was lucky enough that I had brought up my disabilities on the site before so nobody really thought a whole lot of it, but, it's a bit of a cautionary tale, be sure you're okay with your stuff being found if you're going to put it online, even in ways you don't expect.
