Yeah - really interesting video... thanks for sharing...
It makes me think... how will one be able to "rank" high for live content (this might become as important as SEO is now for general indexed results or even more important - who knows!) and how in turn will those changes, eventually effect the values of domains and IDNs
i.e. could "live" content, become a strong alternative to domains & IDNs for traffic flow to a given site (and will having the best "twitter" or "facebook" name become more important than having the best domain or IDN name!)
It's a jump, but obviously one Google and others see this as not just a possibility, but something they need to build into their information handling algorithms right now.
More to learn and pay attention to, in the near future it seems
