People who shout in your programming community that there's "one true way" to do something and gain 'guru' status will either disappear or be telling your/a different community a different "one true way" in 4 years's time. I wasted years trying to do things "properly" (completely pure OO in my case) when I could've been releasing software, and wasting effort anguishing over why I thought differently to the gurus. Now I have no time for programming fads. But try not to go too far this way - it's easy to be too late an adopter too.
