"Because it's popular" is a great way to pick your plumbing, though. The opposite is the awesome developer who is so religious about all the tools and languages that he uses that nobody wants to work with them.
It's a good place to start. But I want to know that the person using a tool has a better understanding of what they are using than "everybody else uses it".
The most popular solution could be the best one. I just want to hire people who think for themselves because I don't have time to do their thinking for them. But first I need to make sure they are really adept at problem solving and can adapt.
