Wave was so cool. I used it to work collaboratively on projects with a friend and it was just great. I was really excited about our wave enabled future. Alas... The simultaneous editing became integrated into Google Docs than in MS Office but I feel like neither really reproduced the magic of Wave. IMO the key ingredient was the chat format: you could go directly from messaging to co-authoring without having to like setup a google doc or send a sharepoint link etc. and then you could keep messaging in the same window. I guess Notion is the modern equivalent? I've gotten burned on hosted notes products too much at this point though.
