I take the guy's point that they are laying it on a bit thick, but I also think he does lambast them a bit too much. Being excited about your company and trying to get other people excited about it too is a good thing.

Describing employees as "rock stars" may not be the ideal approach. But, I'd rather be in a company that's fun with a few goofy buzzword happy managers than one that's precise as hell and every day feels like watching paint dry.
