"Although I thought your article was more thoughtful and balanced, you still seemed to emphasize the communication aspects (e-mail) over the publishing aspects. Despite Lars' assertion I don't see Wave replacing email either. IM with notification filtering might consolidate and simplify the direct messaging app space. I do think Wave could replace Wikis and apps like PowerPoint though my inclination is to let it evolve into something not tied to old metaphors. My impression is that the realtime communication functionality will direct and serve as commentary on the publishing process and that the recorder will eventually be used primarily as a presentation playback engine for the content being produced and not as a conversation playback engine. There's nothing wrong with being an edge case unless you don't realize it." - scott anderson
