Since StackExchange has utterly nailed the Q&A format, I'm just wondering if they are working on any other products?
Context: I recently posted a question to the UX (user experience) site asking for examples of a particular kind of GUI. It hasn't been removed yet, but I know the question doesn't conform to the Q&A format. Nonetheless, I think the question has merit. In this circumstance, a simple modification to the Q&A format to permit more than one correct answer would create a new kind of site, call it the brainstorming format. Feature extensions to the domain of opinion polls could be amazing. Etc etc.
