Your comment doesn't resonate with me.
Have you worked in an early- or mid-stage startup in NYC or the Bay Area in the past... 10 years?
> No offense, but that sounds like some kind of boys club, not professional working environment
That's a strange value judgment; I'm not really sure what to think about it. At the end of the day, the company is still growing and meeting its goals. It is also still facilitating the development of open source software.
So something is working.
> Staying up late = no respect for private life (unless you've signed for it)
Reelio is one of those clients that excited me to show up early and stay late.
They also welcomed my wife and our baby to join whenever they wanted.
Hardly disrespect for private life.
> loud arbitrary music = forced culture implications (why do I have to listen to the music you like?)
Well, sure - this doesn't work in the middle of the day when the entire company is there.
But at 1AM when it's just a half dozen developers?
Have you never had the experience of hearing new music at someone else's recommendation in a teamwork setting? It's a beautiful feeling.
