I use it with my manager to asynchroneously share updates and todos. It's in reverse chronological order, with a big heading for each weekly 1-1. We both write directly in the doc, and tag each other with comments for updates.
An extreme of this, is that some teams (was it Netflix?) basically use google docs as project trackers. The project is described in the google doc, and you talk about it via comments - whenever you want, and as a replacement for meetings (who doesn't love getting rid of meetings?)
In general, the idea with a gDoc is of a central repository of useful knowledge, an improvment over searching through chat messages and endless meetings.
[Edit] The above applies to office environment,where I could see all my team in one place and there were lots of 'hints' that could tell whether I need to have a chst with someone: difficult call, challenging situation, too much work,issues at home and etc.All this is almost invisible when working remotely. Casual calls are necessary to check on people and to make sure they are fine.
> if you aren't speaking with your manager weekly, or really almost daily, then something is very wrong.
I am someone who likes a lot of autonomy.
In-office, beyond my Scrum team, I am otherwise trusted to deliver what I need to deliver. That leads to few check-ins and mostly social banter with my boss as I will be in touch if I require anything. No news means all is well.
It is just that remote removes most of the social banter and problems don't pop up for weeks.
Our larger department has a Monday check-in and a Friday check-in wherein our boss's boss speaks to each one of us—checks in with how we're doing, whether we need anything, if we're stuck or whatever, and also raises questions to us that have come up in their own work. That is often mixed with more congenial banter and chats. Sometimes we throw in a game of Jackbox or something.
My own team has taken to at least a round of something like Counter Strike for the last hour of the day each week. Sometimes almost every day depending on our work load.
Combined with Slack my immediate manager and higher-level bosses are as reachable as ever.
I'm sure once things can safely open up again there will almost immediately be some kind of meet up for drinks and whatever because of course that can't quite be replaced, but I don't think being remote most of the time has to be such a social handicap.
Out of curiosity, why? I have this kind of discussion in Slack fairly often, sometimes in a (smaller) channel, sometimes in direct messages (occasionally with >2 people in in). A quick conversation about an idea, where people can respond as time permits, seems fairly optimal for Slack.
