This is common with people that don't know anything else. So they build biased metrics to put one framework in the spotlight and satisfy their want for using the framework vs learning more about others or building the knowledge to roll their own.

Sure, use a framework, let's not reinvent the wheel. But my biggest peev is when I look at a project with every framework imaginable, using a small portion of it's functionality. I guess this is where the "plays nicely with others" metric is important for these individuals. "It doesn't matter if we load 10 frameworks in the DOM as long as everything works" -Retarded Developer
