I'm coming from a systems and desktop background and looking into a web side project. My only experience with backend frameworks is a few months with Django for a small project at work.

Is Django still a thriving development community? And is it able to handle a large amount of concurrent users? Basically is it a good choice for a backend for a new project? The web tech world moves really fast, and I like that Django has been around for years but wondering if it's still a good option.
