Building on ?response to allow people to respond in the most comfortable medium, the aversion to writing long posts is not just generational. Depending on a person's learning style, they are going to be comfortable writing long detailed thoughtful posts. Other styles, not so much. So I really like the idea of creating an asynchronous space that has options - if you love to write, thoughtful, provocative posts, ?then write. If you are better sharing your thoughts by recording an audio file, that's great too ( I think they can be transcribed for the people who prefer to read)
