Kind of hilarious to see the comments from those who are shocked and offended upon the realization that a lot of us work less than 40 hours a week and get away with it. My unsolicited suggestion is drink less kool-aid and realize your company's mission statement is simply propaganda. No, your ad-based web app is not making the world a better place. Stop pretending that your unwavering devotion to your corporate overlord in terms of hours clocked is somehow a virtue.
