Keep in mind that the internet is a big place, but teh internets are forever. If you're caught screwing up online, you'll never live it down...particularly if it's funny somehow. In other words, when you stand out, do it well.

Also bear in mind that if there is no association with a photo, it cannot be used to identify you except by people who you presumably already know. In other words, if some random tourist (or a kid in WalMart) takes a "crazy guy in a kilt" photo, it is highly unlikely that you will be correctly identified as Joseph Q. McFramenkrantz in somebody's Facebook album.

Keep an eye out for unintentional links, or multi-step links, to information you'd prefer be kept private. Photos of you in others' posts, identified by your username or first name, while your real name sits in your signature line. Some people are comfortable with this...some of us keep the mindset that keeping things a bit hidden is simply good practice, whether we're hiding anything or not. Social media sites are the greatest risk, but can be mitigated. My kilted rear is all over Facebook, but there's no name to match .

Understand and minimize the risks, and go enjoy being the center of attention. There's no reason to live like a paranoiac ...particularly when the vast majority of people you meet are going to appreciate your kilt!
