Honestly I'm not sure why the site comes up in HN so often.
Maybe it's a condemnation of the regular viewership here (and myself), but I find Rachel's posts pretty easy to identify with.
I read it instead as a story about silicon valley companies tend to focus a lot on image over substance. They crate these overwrought hype machines made to market to investors and customers, but then use the same techniques to sell to their employees as well.
Every silicon valley startup has a story about how they're saving the world with their product, when in reality it's just another business that's trying to extract value out of some market.
As an employee I appreciate when a company doesn't demand that I drink thier cooperate kool-aid just to work there. A company that understands that I am there to do a job and exchange my time and knowledge for money. Maybe I've just gotten as cynical as the author over time, but as someone who has been in this industry for 20 years, I don't want to spend extra time at work doing non-work things. I want to get something useful done and go home. I bring value in my skills and experience, and if you work with a company that can't recognize that and wants to put all employees through the same junior exercise of corporate orientation then as the author said, that's a red flag.
They either are a slight cut above, better at some things and worse at many others, or full on delusional. If they're actually much worse, which happens from time to time, then you can joke about how they're head and shoulders up their own asses.
Sturgeon's law applies. The people who know they're a little full of it are usually the ones who have better luck correcting that situation, or at least dealing with the consequences of it.
