As long as we're shooting down strawmen, why don't I write a similar article entitled "technology will not fix your broken business", where I explain why upgrading your app to the latest version of Rails is not enough to make it an overnight viral sensation?

Updating for security or real bug fixes is one thing. Running the treadmill of always trying to have the "latest and greatest" of everything wastes a lot of time.
