Django is pragmatic, secure, and unbelievably stable. It's the framework you choose when you want to build a real business, not just chase the latest trend. It has powered some of the biggest sites on the web, and it's still the best choice for a huge number of projects.
Here's to 20 more years.
Source: me, I was programming in Zope 20 years ago (mostly hated it, although there were lots of interesting things in at a conceptual level), switched jobs at the beginning of 2006 and thanks to the new boss I got to use Django since February of 2006 (I think I still have a 0.96 version installed somewhere on an old instance, still does its thing).
Django and its contemporaries, like TurboGears and Pylons, were a breath of fresh air.
Certainly the release of Rails — and, more importantly, the questions in the Python community about what _our_ web dev story would be — inspired us to extract the framework from the rest of our code and release it. And over the years we’ve taken some inspiration from Rails (as well as anywhere else we see good ideas). The biggest one probably being the basic ethos that web development should be easy — the focus on what we now call “Developer Experience” is the best thing Rails gave the world, I think.
