It's not taught at colleges. It's popular for a few reasons - insanely easy to set up with hosted providers, many of which market at hackathons - mongodb markets at a lot of hackathons - many hackathon projects prefer fast-to-write above all else - schemaless is perfect for an environment where iterating quickly is a must and you don't really care about migrating data - works well with node through mongoose, and node is also popular on the hackathon circuit
