I was on my phone so I wasn't commenting at my best. So to be clear, I liked and appreciated your article! The more view points I can read on these topics, the better it is, because there's no one right answer (as I'm sure you've found).
Yeah. It's definitely a case of trying to do the best job quickly. Validation should be an ongoing process for the pretty much the whole lifecycle of a startup. I think most of us aren't that good at it, or subconsciously avoid doing it, a lot of the time. This is my own effort at trying to streamline that process somewhat.
Thanks for your feedback. Genuinely appreciate it!
p.s. I've read Lean Startup, but will check out The Launchpad, thanks!
