Earlier quoted context omitted.
That site is very out of date. We've been trying to get it fixed (as none of us control it), but we haven't been able to so far. :(
To clarify, are you saying that Rust is web (i.e. that the tools necessary for modern web server development and deployment are available to the Rust ecosystem)?
Depends on what your needs are. I think Rust is ready for certain Web apps. crates.io runs on Rust, for example, and it's a modern Ember-based web app running right now.
I think that the situation is a lot better than that site indicates.
