Yeah I think the possibility of having a dedicated steemit "youtube-like" file hosting site that would allow you to watch random videos sorted by length and topic similar to a pandora would also be a cool thing to look into. The more we make steemit unique, the more interest people will have that are not really interested in cryptocurrency/blogging.
Side note is there a spell checker feature built into the comments/post section? I usually wind up going to google when I see the dreaded red zigzags under my misspelled words. Maybe someone could build an F7 button that allows spelling corrections like microsoft word.
