But I think that the big learning from trying to roll Workplace out to other companies is that it was the FB culture that made it work.

It's also worth noting that even though internal-FB stuff in core FB was absolutely bonkers, it definitely contributed to community formation, as you'd end up seeing that your XFN peeps hobbies/kids etc, so there was a loss there.

Although speaking as someone in EMEA, it was totally, totally worth it.
