Great article by my coworker Daniel Bachhuber on how Automattic can open source more of its work.
I liked this comment by Mark Jaquith, which summarizes pretty well how I feel about it personally:
“What I’d like is for more future Automattic projects to be designed to be Open Source. Even if not completely. There are ways of designing things so that the base code (the framework) is Open Source, but the things you privately build on top of it don’t have to be. Doing things this way will likely lead you to design better frameworks that will not only be externally useful, but will serve the company better. Underscores is a great example.”
