Loaded topic, right?

Was talking with a couple of friends earlier.

One friend was hot-to-trot about social networks. The reciprocity of e-mail, voice messages, text messages, blogging, news networks. How to communicate, how to reach others, what does your "voice" mean if you don't express your voice in public? Does that opinion mean less if you're not "out there" expressing it?

The other friend and I were talking about food/nutrition, body image, cultural definitions of self-esteem or beauty or health. It's another type of "voice" by what we show to the world, or what we keep secret in dysmorphia (anorexia or bulemia). Does that opinion mean more if you're "out there" expressing it?
