Huh? We’re talking work chat, right, with technical content and project specific stuff etc.? I refer to that all the time. I moved work chat from ad-hoc social media onto an internal Mattermost server explicitly for this. And at the time it doesn’t seem that useful, but it’s the long tail of projects where it really saves you. Being able to quickly find that one thing you’re sure you discussed that one time three years ago on a project that was closed out two years ago? Priceless.
