Buried towards the bottom of the essay is the fact that the author has accepted a full time offer from Facebook. So yeah, the last year of college (and a degree stamp) is meaningless as long as he plans to stay in the tech world.
This person will get a rude awakening when they need to go the next step and realize "almost a degree" isn't really a degree.
I have heard the TN visa for Canadians allows you to substitute something like 3 years of work experience for 1 year equivalency of a college education.
