I've seen it growing in popularity firsthand. The projects I'm involved with have seen large increases in contributors, mailing list activity, traffic on Github, downloads on PyPi over the last four or five years. PyAtl and some of the other local groups with Djangonauts in them have grown sharply over the last two years (in the Atlanta area). People from other backgrounds are more likely than ever to at least have an idea about what Django is (whereas when I was starting back in 2006 people would just stare at you).
I like playing with Go and the other newer/trendy stuff, but the thing I like about Django is that I can just sit down and get work done fast. It's not sexy, it's not clever, it's not magical, but I don't want it to be any of those things.
As a side effect of this, a huge percentage of the population is too busy getting stuff done with Django to blog and interact, aside from asking questions and getting advice. You know, like Instagram, Pinterest, NASA, National Geographic, Disqus, Mozilla, The Onion, PBS, and many more.
