Not every language has to have webdev functionality shoehorned into it. I hardly think that having more web developers involved would speed up the development of the high quality scientific packages that Julia contributors are already currently working on. The people the Julia community should focus on attracting are data scientists and researchers in quantitative fields. That being said, the guys at Hackerschool are working on a web framework for Julia https://github.com/hackerschool/Morsel.jl.
Oh and major kudos to the Julia team. This is a seriously awesome piece of software. The decision to write most of the runtime in Julia itself and rely on a solid JIT compiler and simple FFI to get the necessary performance was very well thought out.
