I'm in full agreement with this. The learning curve (and the compilation speed I guess--but that's improving quickly) is the main drawback to writing Web apps in Rust. If you've already learned it, though, then it's basically just down to the typical static vs. dynamic typing tradeoff, with Rust just being like any other statically typed language.

Rust's errors handling and memory safety are important differences too.
