Customer traction.

Are the people you seek to serve eager to engage with your work?

If yes, do you want to keep them waiting?

What's the minimum WOW version you can make live now?

If they feel the wow, would they be eager to bring their friends in?

Wow doesn't need to be perfect. It might need to be magical.

You can keep working in the background, dotting the i's and crossing the t's, but does your audience care about that?

The hard part is customer traction.
