I have been using Slack a lot in the first half of 2018. Multiple servers, different people, customers, everything. In recent months it looks a lot like slack is slowly dying as activity is far less then it used to be. Some of the servers I participate are already closed down and moved on to other services.
Since I first used slack I really couldn't get comfortable with it. It just has a few things that just don't work like I want them to (e.g marking a server read, handling of servers and users). That is why my company used Discord from the start and not the then "industry standard" slack. Also, all these integrations are nice but I have jet to see a useful usage that people actually use for a longer time.
So I came to the conclusion that slack is dying a slow death, if they don't change some fundamental things.
