Yes, the media Creators can earn rewards, the people who leave nice comments on the videos/podcasts/media can earn rewards, and the Hive-Tube site hosts can earn rewards too.
Thanks to the Hive blockchain we can even automate subscription payments to the media Creators as well (adios Patreon!).
The HiveCast mobile dapp basically acts as a "Tuner" to thousands of media channels across hundreds of Hive-Tube based websites.
