This will be an interesting one to see, how Google's Wave application or platform is adopted. It is ambitious. On it's surface the screenshot makes it look like some form of new social network, and that is where it could be end up. But the intent is much more profound. It is like these guys got started and just couldn't stop. It is amazing it works at all! –IM / E-mail integration for people online –in line editing of documents –image management –playback of all changes and gadget events And all opensource with ability to be hosted or used as a service. Can't wait to get an account to work with. Need to bribe a google developer.
