Truth is that Unix has a very good design for an operating system, that gained large popularity, and will be in widespread use throughout the foreseeable future, because of the superiority of its machine model and design.
No matter how many blog posts there will be to try to diminish it into an operating system for some religious cult, and weirdos. It is still the best platform. I hope that many more users will benefit from it in the future, as the philosphy behind it is so much more user friendly, and practical than most other Operating Systems. Read me right, I am talking about having Unix in the core of the OS here, not just to present a user with a shell.
