Technical skills *alone* is not valuable, correct. But if you find ways to ensure whoever coming to your website will generate new users and stay (virality factor) and also grab publicity at the right moment, and you understand what "right moment" means instead of naively going to TechCrunch while your website's fundamental design is not all that viral and not all that usable (e.g. the Color app that got $41M in investments) - then, only then, will you have some chance of success.
In short, it's all about execution, and most people think it's simple.
