Like everyone else has said, use what comes naturally to you. It all comes down to your users and if they like it or not. They are not going to drop you for using php instead of Rails.

On the other hand if you are like me, I have an idea and I want to implement it. But if it fails I alteast want some new technical knowledge. For eg, I learn xcode and write an iPhone app and it bombs but I know iphone app development and that is valuable.

The way I'm tackling my tech stack dilemma, is to look at other successful websites find their tech stack and see if that fits my needs. Good luck!
