Wow. Philip Greenspun is a name I haven't heard in quite a while...

I used to work for that guy...

Anyway, nakedness: my own experiences with having naked pictures of myself online have been nothing but positive (but they were porn, not art, so that's probably a bit different...) It's been good for my impression of myself and my body. Even if nobody says anything, the act of sharing is itself quite empowering.
