Mongodb still comes up a lot, if you hire a team in South Asia for instance it's very likely to be based on the mean stack. It works great when you're doing demos and beta testing small customer sets but it has a lot of trouble scaling. In fact, I've made a bit of a career catering to that exact situation. I just happen to have taken a dislike to SQL so I hopped on the nosql bandwagon early. Now, I'm an expert at creating complex indexes and helping people enforce schema and rationalize their operations. Often times, postgres is brought into the mix as a hybrid solution and over time dependency on mongodb can be reduced or eliminated.

Look, the alphabet soup of technologies that we read about here on Hacker News don't really represent the reality of what gets put into production and actually works. There are really only about four or five stacks that really matter, I'll leave it as an exercise for the reader to figure out which ones they are.
