The approach is appealing, not sure though I understand it correct - you mean we create communities on Reddit (so subs) or here on Hive or both?:
If we create these communities, some Hivers can join them too and we might get more engagement below the Hiveposh posts. Within communities, we can also incentivize Hivers (for example, comment contests) to join discussions below news posts. This might help to create discussion below popular posts which will be helpful for onboarding...
Sorry, missed this comment. I talked about Hive communities. Have you joined many websites, forums, and social media in your life? What was your motivation each time?
It could be
Thus, community and engagement (due to communities) make onboarding more probable. Secondly, a community can be onboarding-friendly - with some extra hooks to onboard a user.
Sounds cool - so my personal reasons / motivation would have been 1 and 6:
Apart from onboarding here via communities I also would try a bit more (based on comment by @theworldaroundme ) to drive / control conversation on Reddit. We sometimes get negative feedback and instead of saying nothing we should engage more.
Sometimes we get good views but hardly any engagement there - testing now to drive this a bit.
Think we should consider both ways - onboarding help via Hive communities and also engage on Reddit shares itself.
