Steemit if full of upvoters freaks .. not caring about the content and using the platform only for swap upvotes and resteems in order to boost their own account ... Steemit is becoming useless for content ...just look at the comments on popular posts then you will know what I mean ... Dtube on the other hand is a little different and is slowly becoming a good source for content.
I am not sure about Dsound yet ... if users are there for content sharing and engagement ... or simply for boosting their own accounts ...
