You made some very good points.
Regarding the crypto based music platforms, I agree with you: None of them a success, and I think none will become a success. They are all made for artists, not for the fan. But without the fan, no audience for the artists therefore no success for the service. Only when somebody sees the light and create a music platform that is super for the fan, it has chances to win. Think for instance: Bridge soundcloud through a crypto rewarded music platform as an extra to own content. Or strike a deal with Spotify or TIDAL, to mix their catalogue with own content. Next to that, provide the compeling features a music fan is looking for.
Would be great of FB experience can be converted to ReggaeJahm, for instance. This is not only blogging, but also includes an ecent section. In crypto space, the Slovenian based Viberate created something really interesting. They dont have a blogging section yet. I had the opportunity to talk with the CEO behind this service, but didn't do this, because the dynamics of HIVE doesn't fit the professional approach of Viberate. It's a shame, since the promiss of HIVE could very well benefit Vibrate service.
