A tough part about slack is messages deletion after whatever time frame. Not sure what the pricing policies are but even the enterprise account I use for work deletes (private maybe?) messages, and separately the free tier do as well. (maybe the company is just cheap) I'd personally not care too much if it's slack/forum like platform but my biggest request/need is message persistence - especially for professional/enterprise use Edit: it's interesting to think about a private Overflow instance being used for work comms. - can't even really visualize how that'd work because i always navigate to stack overflow topics via search engine
