This post was discussed constructively on the Julia mailing list some time ago, and spawned a long and interesting thread. Worth perusing for some followup.

The authors seem very receptive to feedback -- which is encouraging. Maybe I missed if they addressed this, but I wish they'd consider the IDE to be an important part of the language ecosystem. A web REPL is good... but I suspect that (despite Steve Yegge's prediction that the browser is the next IDE) that programmers will expect a serious language/environment to be called interactively through emacs as can R, matlab, and python/ipython (I heard vim can also do this with R?). Or, possibly through an IDE like Rstudio with optional local/server access.

I expect the Web REPL will ultimately evolve into something like RStudio (which itself is web-based, even in local mode).

There is already an emacs mode for Julia: https://github.com/JuliaLang/julia/blob/master/contrib/julia...

Emacs mode already? They're doin it right. :)

I was not aware RStudio was web-based. News to me...

Yep, RStudio is GWT driven (https://developers.google.com/web-toolkit/) and uses some very particular configuration tricks to keep you from accessing it with a browser in local mode.
