That stands for “Open Source Innovation”, and Dana Blankenhorn suggests there isn’t any. Uh... Apache. Emacs. Vi. Perl. Python. Ruby. PHP. Those were the result of twenty seconds thinking. I don’t think software innovation historically has correlated negatively or positively with open-source-ness. In the future though, I think pretty well all software innovation will be either open-source or inside a big server, because the business model for shipping closed-source software as a product is just too twisted and weird.
