This is what things like "water cooler chat" looks like for remote-first. This is the fundamental difference between what a healthy remote-first company starts to look like versus the soulless version historically in-person companies try to sell. To the author, thank you for sharing your version of the dynamics.
It also shows that remote work requires work to work out. You simply cannot bump into your colleagues, so socializing needs to be planned. On a small scale, a regular coffee talk might work. But I love the idea of this being more of a "pull". Like, everyone can consume it at their own pace.
