I think we need something that could be called "The good parts of the Java/Ruby/C#/Javascript/... ecosystem". Showing what tools and libraries are recommended at the moment and how some of them work together. In Javascript the ecosystem is growing almost exponentially which makes it impossible to keep up with everything. In Java and C# there is many old classes still in the libraries and around that most experienced developers avoid. And some trimmings of the ecosystem would probably be useful every 3-5 years or so.
