Shamelessness by itself won't take you anywhere.
Take the Paris Hilton story for example. It was never about Paris, but always about the public. A certain perception of her made the news, so she just played along and amplified.
Same for the Merlin-as-Percival tactic. Don't try it with a bunch of kids.
Since people here like to start companies: it's never about you, your idea or product. It's always about the others, their feelings, their perceptions, and how you are able to play along an amplify.
