During my commute I pass Groupon's Palo Alto office every evening (I only go this route during the evening because it's closer to my gym). For such a large and publicized company, their building always seems empty. I never see people going in or out. I always see empty conference rooms in the window. Perhaps this doesn't reveal anything about the company, but the view from outside (literally) doesn't compare to what I see when I pass other tech companies in the area.
