I've used them collaboratively quite a bit. They are a quick way to talk about different players you are working with and talking to, and the layout of the canvas gives you a common vocabulary to talk about how you are viewing different players. Early on at my current startups, we were doing quite a bit of discovery and talking about a lot of different organizations and a lot of different relationship options, and the canvas gave us a way to keep track of that while we were working on other things. We still keep one up to date and use it for on-boarding and documentation of learning. It's not a heavy-weight process. Super light-weight. If you get too formal about it, it's a waste of time, like UML.
