In my opinion the interface of these websites is one of the most important factors in retaining viewers. For example Dsound doesn't produce as much revenue as say Steemit.com or D.tube, and I think one of the reasons for that is people are a bit off put by the interface. They still don't have playlists, or even a search bar. You can't even search through tags unless you click on the tag on someone's post. I like Emanate, but I hope Prc gets back to updating Dsound.
