I would say that the MEAN stack craze is long gone. When I started developing, it was the next big thing which everybody wanted to learn. Now when some time has passed, people see the problems with it, mainly Node and Mongo. Turns out that it's nicer for more people to use a statically typed backend language and a relational DB, so we are back where we were before MEAN, but it sure was fun stuff when it was new.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
