I don't know if I'd agree with that - I haven't worked at a company that uses them, but I have seen them all over Facebook, and they don't look like they're failing anytime soon so far.
Oh it gets even better. You can't even find the best ones in online pictures I think. They have an auditorium with floor to ceiling banners everywhere with those slogans (and those are the bold white font on red background I was referring to). All that's missing is Stalin preaching from a podium. Zuck pontificating on the "knowledge economy" does give him a run for his money though.
And lest anyone mistake me for a hater, let me be clear that I have a tremendous amount of respect (even awe) for the information empire they've managed to build. I do question its value however. I know few (if really any) people for whom Facebook has been, on balance, a positive influence in their lives.
