During his keynote, he extended an invitation to any open source application to submit their software for testing by user-experience experts. The sessions would be recorded for posterity, and the developer would not be able to interact with the user. “‘If the developer is in the room, they have to say nothing. It’s the shut the f*** up protocol,’ Shuttleworth said. ‘You sit and watch someone struggle with the software that you’ve so lovingly produced.’”
Mark Shuttleworth is the men! I think Linux (or just any OpenSource software) should improve their usability and so does Mark Shuttleworth.
