It takes too much space, even pictures are not stored on steemit, only url's, thanks for the vote brother :-)

Visio is not just for solely videos, its a distributed platform that can host files of any type so it will be left up to the user in what use case they plan to use the platform. You can kind of view Visio on a few levels, one as a distributed system to deliver content with no middle man, another view is a platform for users to build on to create a home for their audience and a censorship free spot in a form of like Youtube and sharing platforms but the user can put in options of how they want to earn either through the bounty system in place or ad overlays. Main thing like @bubke stated is space, our masternodes will be the content storage centers but in a decentralized manner so its not overly censored or some central system banks income off of the users for their work.
