0.1% of people in the world? That seems a little high. 0.1% of people who describe themselves as *-dev? That seems really low. Also, how do you define "need"? Dtrace isn't just for tracing functions down to the kernel level, and I can imagine all sorts of things that a web dev would find useful in dtrace. Just google "ruby dtrace".
