Startup culture is not Razor scooters, pool tables, free snacks, a DJ table, a ping-pong tournament or dogs at work.
While I am all for “startup culture” infesting big companies (i.e., Zappos SF, the Wallmart Labs, NYTimes Labs, etc), these things are not what makes startups “startups.”
The freedom to engineer and implement rapid solutions to real problems with whatever means necessary. That is the “startup mojo” you seek.
All these other accouterments just let that happen in a more enjoyable way.
