Looking at the UI screenshots and hearing this person's experience, I imagine this will be used for awhile only by the elite digerati until they really streamline the interface and come up with a better metaphor of what this is. Also, until you can talk about solving someone's problems with it or why it's better than what they have now succinctly, it just seems like another cool toy cooked up "in the lab" and that's not necessarily a recipe for widespread adoption. Even now I've read a fair amount of the Google propaganda and other's posts about this and I'm not sure why I would suggest our team move away from the tools that replicate a lot of this functionality.
