I'm rebuilding this site right now. So a lot of things may look broken. But what better motivation for me to finish it?

The danger in prototyping too soon is investing resources in answering a question no one asked, and ignoring the opportunity cost. Testing a prototype can help you refine an idea that is already good, not tell you whether you’re solving the right problem. And it’s easy to mistake the polish of a prototype for the quality of the idea. FWIW, it’s also easy to mistake the gloss of a research report for the value of the insights.
