I love this post by Shanley Kane:
Let’s examine popular startup trends that are being called “culture” and look beneath the surface to find the real culture that may be playing out beneath it. This is not a critique of the practices themselves, which often contribute value to an organization. This is to show a contrast between the much deeper, systemic cultural problems that are rampant in our startups and the materialistic trappings that can disguise them.
It’s thought provoking, bang on the money, and worth a read.
