My biggest question about remote work is how do you get the culture and knowledge-sharing-through-osmosis (that is, unconference style chats at the watercooler or the pub after work or whatever informal knowledge sharing that happens)?

I work from home 3 days a week, so I still have enough office-face-time for that not to be a problem, but we have a lot of 100% remote workers too (who aren't even in the same country) and who get left out of a lot of informal conversations just because they don't happen to be there when a group of us walks to the shop or whatever it is. We do fly everyone over every few months, and those periods are fantastic, but I still can't help but feel that the remote people are losing out and the company is losing out on their input outside of the normal work stuff.

Would love to hear others thoughts and experiences on this and ideas on how it could be remedied!
