I think the fact that both (Musing & Quello) platforms required Hive to curate it was quite a tricky one as it follows both of their mission statements to reward valuable questions and answers and although I still definitely believe Hive is vital to this too, an additional token allows for another dynamic for that and opens up a range of other utilities to make the platform more dynamic. Although the first version will be Hive only, it won't be long until we put forward a few initiatives we'll be introducing to try and tackle this.
