Thanks for your answer.
I think your idea is good and has a lot of potential.
Don't get me wrong. I understand what you say, but still I'm not sure I get what the relation with YC really is. To me it doesn't matter if I make it into the startup world with or without YC, it matters if I make it. And YC is not as important for the funding, as much as it is for the advice and the experience.
They could help you avoid making mistakes.
Best of luck with Persona! I think I'll sign up.
