working at a fully remote company, this happened all the time in slack. people used slack constantly, socially and professionally. channels filled up with context, and it was not only easy but asynchronous to search or even just go back through a day's unread posts in a channel and see what things happened, reply about something, copy it over to a colleague and get them involved, hell even spin off a ticket from it with an automation. people were in hundreds of channels, and it was a firehose, but teams helped each other make the most of it
then we got acquired by a much larger onsite-first company, and their slack is dead. nobody posts anything unless they absolutely have to (i.e. "the men's toilet on the 3rd floor is overflowing" at least twice a week, or that some printer needs paper or toner). there aren't slack bots because nobody checks slack. everything else happens in person, in a servicenow ticket, or at most via email
their IT team has no idea how to support how we used slack before. in one case they told us to stop posting in a channel used by other parts of the company because we were generating too much disruptive activity. I can see the team cultures around it eroding week over week, but we're not in any office, so there aren't any in-person behaviors replacing it. we're all simply becoming increasingly isolated, losing track of each other both as people and in the work we're doing, and becoming unhappier and less effective
this shit isn't hard, but it requires effort and people who see the benefit of it. there's a perception that people with remote work skills can just roll up into an office and be as effective without changing any fundamental aspects of how they work, and vice versa, and it's all bullshit
