Note: This is NOT a "what would my cm be?" thread.
Yesterday, I began wondering what would happen if people had cutie marks. Just like in MLP, they'd appear when one finds a talent. It would probably be on you arm, not on your hip. I'm not wondering how it could be made a reality, so please don't even think about it. Also, I'm not referring to humans as in EQG, I mean real-life people.
I imagine that it would be a game-changer for jobs. Since it would prove what you're talented at, it would show people if you're good (or bad) for a job. It would be like another college degree. It would also help you in decisions, since it would essentially foretell your destiny. It'd be funny to see what politicians' cutie marks would be.
Also, it would probably be a big thing to have a unique mark. For example, if someone became the first person to get a video game cutie mark, they'd get a lot of attention.
Any other ideas?
