Nice video. I'm just as excited as everyone else, but I do have a few questions about this:
Can the STEEM blockchain handle something like this? I don't know a lot about the technical specs of the blockchain, but if this actually sees widespread adoption blockchain size and transaction count is going to explode... (This could be a big problem, but is hopefully unfounded.)
Won't the verification process turn new users away? Personally, when I'm going to leave a comment on something, I want to do it immediately. It seems like new users might be discouraged from commenting on a post by the long verification time (or fee) for creating a new STEEM account. (This seems like less of a problem, as once a user has an account they can use it everywhere.)
That being said, this is a great system. Can't wait to see it being used!
