At work we use Slack, Email, Google Docs, etc. We’re never quite happy with how things work - what should be email vs Slack, at what point should a a Slack conversation become an email conversation to be visible to more people, when should that turn into a doc for a more formal review process, etc. We’re trialling Notion for some things and it’s good. What should be a Wiki?
Whenever we have any of these discussions, I always feel like we’re circling around what Wave once was, and potentially could have been. It wasn’t fully polished, but so many of the fundamental concepts were there. If it had stuck I think communication in companies would be much better than it is now.
