I really like the idea. It has some really difficult challenges to overcome though as cryptos points out. But also most of the content wouldnt be suitable for hosting on the steem blockchain. I wonder if storj would be able to host the content and then you would place any relevant transactions on the steem blockchain. Im not sure blogging would be the best media for VR. But like you said, other types could be really cool, and interacting with other users and content might be more interesting.
