It seems self-exposure, or assertively forgoing privacy, is for teens "as natural as brushing their teeth," writes Janet Kornblum of USATODAY. They seek feedback on themselves constantly, Janet quotes one expert as saying. Another told her that teens understand privacy but simply choose to be "out there" because that's how things happen. It's about marketing. Or just staying in touch, which outweighs the potential downside (reputation issues). So they just develop a thicker skin and/or learn how to manage their public persona (see "Online spin control").
