Ask HN: Do employees at large companies use internal forums instead of Reddit?
Maybe they do this even when discussing non-confidential topics?
Most companies have some dicussion software such as Slack/Teams, but some enterprise companies do offer forum/wiki software for collaboration (e.g. Atlassian Confluence)
There’ll be channels to talk about random stuff, or about fantasy football, or to post pictures of their cats, or whatever.
I’m not sure why this is even a question?
Do you have any particular topics in mind?
But if you have a very specific topic around, you can create groups with Teams.
