Ask HN: How do you validate your ideas?
How is this done in practice though? I was working on a project with a friend a while back and we posted a landing page with a mailing list here. The feedback it got was along the lines of "This is just a landing page, come back when you have a product".
How can you get useful feedback and validation on ideas without spamming links to meaningless landing pages everywhere?
I look forward to hearing your views.
