Gamifying interaction is awesome.
I like the subscription idea, especially gamified. It could even act as a catalyst to bridge more real world things into HIVE since its a social blockchain at its core. I love interactivity between real humans, heck i even bought HIVE 3d etched dice 5 years ago and I've been working on a few front end ideas which bridges the idea of HIVE users interacting with some of my own personal real world devices, such as my GPU for inferencing or my 3D printer.
A maybe sub service which nets the subscribers little figurines from a 3d printer or allows the generation of music or art. (thanks for the vote btw!) Or even lets you send little 3d printed figurines to content creators you support, that might be interesting. I like your collectibles idea, I'm just wondering if it could be expanded beyond the digital realm....
I'm glad there are people like you focused on the digital realm, the back end operations of HIVE seem like complex wizardry to me, so thank you for that!
