These should be default CREATOR/COLLABORATORS services (for a fee and reward of course) but as a somewhat closed system/community they don't really add to Hive they just make sure cross interaction is difficult.

As a backbone fundamental it would be interactive multi-community engaging.

For example a person writing a cooking post wants to represent origin of their ingredients, they don't go and do that photography themselves, but if they can then tap into the work done already by a photographer, or even put out a "need media" request it would drive engagement between many worlds that exist here.

With that even mediocre services such as a banner for a new post or a new avatar for a new user could all be gamed and generate rewards for all kinds of Hive users. This is happening here and there so that's my point, that as as backbone system it brings it all together.

Anyway maybe I'm too visionary.
Maybe Hive will always be:
SHARKS cleverly capitalize.
SHRIMP shrink their holdings.
