Anyone with a little bit of Apple history knows that it is merely an allusion to the Think Different marketing campaigns that Apple used to run.
"Here’s to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes.
The ones who see things differently. They’re not fond of rules. And they have
no respect for the status quo. You can quote them, disagree with them,
glorify or vilify them.
But the only thing you can’t do is ignore them. Because they change
things. They invent. They imagine. They heal. They explore. They
create. They inspire. They push the human race forward.
Maybe they have to be crazy.
How else can you stare at an empty canvas and see a work of art? Or
sit in silence and hear a song that’s never been written? Or gaze at a
red planet and see a laboratory on wheels?
We make tools for these kinds of people.
While some see them as the crazy ones, we see genius. Because the
people who are crazy enough to think they can change the world, are
the ones who do."
Any choice of name would be down to personal opinion and preference, but I think it's far better than any of your suggestions which are all too narrow in there descriptive ability other than AskApple, which has trademark and copyright issues. Using "exchange" brings to mind Microsoft, to me. As you can see, logos and slogans etc have to be chosen very carefully.
