Why use your real name if you don't have to? If nothing you post can come back to bite you in the ass later, why not stay under a nom de plume? I am finally starting to think Facebook and it's real names are a bad idea. A really bad idea. The only advantage was finding old friends. What advantage is to revealing your real name ?
Is it enough to not disclose your real name? A pic of you is much more solid identifier that your name..
