Vanity, thy name is everybody. We all obsess over the way we present ourselves online (I know I'm not the only person who carefully selects and crops his profile photo), but some people take it to another level, hiring professional photographers and retouchers to take profile pictures for them. Sites like LinkedIn are especially susceptible to this, since appearing professional is paramount on a business site, but I've even seen this tactic used on Facebook and unconscionably, I think on online dating sites like OkCupid and others. Sure, this approach might look good, but some social media experts warn that too professional a picture can be off-putting; customers and friends alike want to believe they're dealing with a real human being.
