Judging by these comments, everyone is writing web apps in Rust these days. While I can understand the fascination that many HNers seem to have with Rust (been wanting to give it a try myself for some time now, but work and life always get in the way), I'm still not sure web apps are really a good fit for a language that has a reputation for being high performance, but more difficult than other languages commonly used for web development. I mean, you wouldn't build a web app in C/C++, and not only because of the potential security issues?
My primary reason for moving was to capture the advantages of a strongly-typed language. I suppose Go would have been another reasonable choice in this regard.
