Have heard this sentiment in more than one comment in places like HN. "The {tech} is great, but the culture was ... so I'm not putting {tech} on my resume". And So it becomes a self-fulfilling prophecy :). Yet some tech seem immune to this. They don't say "X is great but the culture was crap, so I'm abandoning X", they say "X is great but the culture was crap so I'm changing jobs".
It really drives home that culture is critical, and even the worst tech can be tolerable if it is thought of as cool. Though of course the thought of abandoning ship to learn the latest and greatest solely to avoid legacy C++98/Spring/WebForms/whatever is naturally appealing.
