About the only thing I agree with is how great their docs are. * Mongo is only easy to learn. Beyond simple demos, it gets harder and harder to use as projects evolve i.e. you have to do a lot of work yourself imo this is a common problem with nosql datastores that isn't exclusive to Mongo * "Document databases can be great and flexible solutions for some kinds of projects": Postgresql has been able to work directly with JSON for some time now. There are also other document datastores that are more reliable than Mongo * Scaling with Mongo is difficult, specifically the crazy setup. Even if you set it up properly, the results don't tend to match the marketing https://aphyr.com/posts/322-jepsen-mongodb-stale-reads https://aphyr.com/posts/322-jepsen-mongodb-stale-reads * "arguably quicker to get a project off of the ground with than traditions RDBMs" unless you're using Meteor, I'm also going to disagree here. Most frameworks target a relational database by default. Developing by convention tends to get you off the ground much faster than using something more specialized and niche
