Validation is often oversimplified.

Driving traffic to a landing page validate's that you're good at marketing; signups validate interest from consumers; feedback provides insight for product development. However, none of these actions validate your idea.

Product demo videos provide people the context they require to properly assess the value of your idea. The best demo videos quickly describe the value of the product and then provide a use case which creates context for the audience. Finally, they end with a QUICK walk-through.

Drew Houston launched Dropbox with a product demo https://www.youtube.com/watch?v=7QmCUDHpNzE. Try to think of validation as an ongoing process and product demos as the next step.

"Validation is often oversimplified."

100% agree. It's very difficult to get "honest" feedback without getting a product in the hands of users.
