I'm pretty sure every company I've ever worked at has been in the middle of trying to fix their document management & sharing. It's all sucked. The overall best knowledge-base I've ever used has been... Slack :-( Email is probably second-best but suffers from too much spamminess—"here's a progress report you don't need, for that project you're kind-of on part time, sent once a week, to pollute your search results for same project if you ever actually need anything, oh and there'll be a 20-reply thread here which may or may not contain anything worthwhile to anyone at all, good luck sorting wheat from chaff". Plus if you have both Slack (or similar) and email Slack's more likely to have the Real Stuff, and email may miss out on entire topics.
