yes steem could be very beneficial to existing or still to be made platforms. I love it here at steemit and can see steem as a currency really getting the engagement back into the social world here online. It would always make for a great youtube replacement. Instead of getting paid by ads you could be getting tipped by the people that actually care about your videos.
Lots of possibilities with steem! I'm here for the long haul so lets see those prices rise :)
