Thanks, Sarah. I agree that we need more feedback from a broad range of users. It seems difficult to get feedback from those who are using WordPress but not actively following developments. Putting out a call for input probably won't be sufficient.

So, maybe using people who interact with lots of users in the various segments would provide a proxy. It should be possible for the Guttenberg team to reach out to people who are training new users and others who work extensively with designers, for example, to get input.
