> easier than ever to learn to build industrial-strength products Well, ok, it might be "easier than ever", but it is still very hard. Just see how relatively niche applications like github are struggling and how out-of-the-box tools like RoR or Mongo have frequent issues. I would compare building web apps to driving boats: doing a simple prototype is sailing a dinghy in good weather at sight from the coast. It is easy, but scale it to "industrial-strength" and you are lost in nowhere under heavy storm: you'd better have a better boat, which means a bigger one, those that have more momentum, and then you cannot jibe anymore, you have to do proper by-the-book tacking, which is slower, safer, less cool, old fashioned, and all that.
