It amazes me how popular Slack is. Terrible performance, constant interruptions, horrible threads. Here's an exercise. You and your coworker discussed plans for a project in a large channel 3 weeks ago. You need to get all that information and give it to someone else. How do you do it? You can't. It will be interspersed with a bunch of other nonsense from other people and isn't grouped or organized in any sane manner…
What's the alternative though? I really don't like Slack but I don't see another great way of doing it. - Face to Face: No record, even harder to give to someone - Wiki: Goes stale pretty quickly - E-Mail: Same problem, slower, as distracting as Slack
