Nim is an excellent project but its ecosystem is too damn small. Besides the core devs what Nim needs is small companies that try nim and release more and more quality pkgs like yglukhov did with his Reel Valley project.
If you do not have the resources to build something like that do small screencasts, write short blog posts about what you think are cool aspects of Nim and how did it help you to achieve your goal. Other than that we need 1.0 and a continuous development for the C/CPP and JS backends.
