Even when demos went well, there was always a steady flow of feedback, suggestions for changes, impressions on how the software might behave differently. Everyone spoke up. Demos were an open forum for exchanging ideas about how an interaction might look or function better. When demos went poorly, as sometimes happened, there was the same stream of comments and constructive criticism. There was never any finger-pointing; however, there was an expectation that new demos would include a response to the feedback from previous demos. This was the one essential demo expectation: progress.
