Have you ever been at a banquet or in a boutique or at a concert or a meeting or a company where the vibe was incredibly positive?
If vibe is so important, why does it sound flaky to worry about it? Who's in charge of the vibe at your place? Could it be better? A lot better?
This is a very real and under-appreciated part of work. It was one of the first things I noticed when I started at Google after working at Intel -- the place just felt so much more alive. Now it's something that I watch for when visiting startups -- my guess is that upbeat and energetic companies will outperform the ones that feel oppressive and hopeless.
