I understand the reasons, I just don't embrace them. I couldn't care less if someone I know recognizes me on this site. So I'm on a men's clothing/style/fashion site. It's not like I'm looking at child pornography or something. But I'm not trying to change anyone's mind. If you're more comfortable hiding your face it's no big deal. I just want to see your clothes. But I do have to say, there is a context thing going on. Seeing your face/age/etc. definitely contributes to the assessment of what you're putting together and the positive comments or constructive criticism that might ensue.
