Yes that makes sense to an extent. The problem is that people were insisting on using MongoDB for problems better suited to a relational DB when it was faishionable, and now that decision lives on 6 years later. Or I see a lot of CV's where people collect web frameworks - which essentially do the same thing. Yet whenever I inherit Django code, it seems to be done by someone with only the most basic knowledge of how to get things done.
