To me, being able to make changes to your code while keeping the current state in the REPL is key to interactive development.
My workflow is generally to build up state, and then experiment with functions on that state until I get the correct output.
This workflow is very natural in Clojure, Common Lisp and even Python (with IPython and autoreload).
However, in Racket you have to restart everything on every change. This works ok for smaller applications, but if for example, your state is a large dataset that you pull from a remote database, it becomes a little more difficult.
There are possibly workarounds, and I'm not saying that Racket is bad because of this. There are definite advantages to this approach, mainly for keeping everything simple and predictable. However, this was a roadblock for me, and the main reason why I didn't spend more time working on it.
I also miss the ability to make changes to code, refresh the browser and instantly see the changes (instead of having to restart the server after each change).
Thanks. Do you know if it works with the module system - for example, if I edit function definition in a module, and then send that module definition to the REPL, would any code using that module start using the new definition?

Here's a good discussion (in my opinion) of what makes a good REPL for interactive development: http://vvvvalvalval.github.io/posts/what-makes-a-good-repl.h...
