Have you thought about the fact that just about every time Steve Jobs appeared in public, he was selling us something?
And yet few rolled their eyes and said, "oh, here comes another sales pitch."
Jobs sold us expensive, high margin hardware that we knew would eventually become obsolete, and yet people lined up to hear the pitch. How come?
I think it's because he was saying:
"Here, I made this. It might be worth talking about."
Inherent in this statement is the flip side, "it might not work."
And in almost every case, he was right. That it might be worth talking about, and that it might not work.
In almost every case, skeptics pounced. People discussed his work.
Sometimes he was early, but he was usually interesting. That's a slot that's available to more people than ever before, regardless of industry or audience.
Average stuff for average people is getting ever more difficult to sell. If that's all you've got, get something else.
