I’ve heard the Lean Startup methodology likened to a framework. Its central precept is that a startup should develop its customers as it develops its product – that is, both concurrently and in a structured, concerted fashion. If you’re taking advantage of a framework like Rails for the latter, you shouldn’t be using the business equivalent of compiled Java for the former (or more accurately, cf. Waterfall, Agile). It’s about mitigating risk at every decision point. It’s a floor wax and a dessert topping. Even use it for your blog.
If this post was a candy bar, it would be something like a Super Snickers with more nuts, caramel, and chocolate than anything on the market. This is a super lean startup post that has enough links to keep you busy for days reading up on how to at least not completely screw up your startup.
