Putting Yourself Out There

How likely are you to subject yourself to any kind of public scrutiny?

A few threads led me to this question:
* Following our most recent conversation, thinking (again) about my daughter's choice to be an actor.
* Listening to four CDs a good friend made featuring his original music.
* Noticing a book on my shelves written and self-published by another good friend.

Although my threads all happen to involve people putting themselves out there via the arts, there are many other ways people can subject themselves to public scrutiny, e.g. politics. If you have never thrown caution to the wind in this way, what prevents you from doing so?

I suspect most of us would agree making oneself personally vulnerable is difficult. In your view, how does public vulnerability compare?
