Again, I couldn't agree more with you!
I think this is one of the most important things for us to talk about now, specially because we can already see an increase of users.
I did some suggestions on this post a few days ago, and have been think about it since.
I totally agree with you and @caluman about it being simple, so I thought about shortening the authentic and inspired words, like this:
- auth-hobbies, auth-story, auth-media
- insp-belief , insp-creation, insp-ideia
But on the other hand, although you say that is not the most creative one, I have to agree again with @caluman that add just the POB in front of the tag can be a teaser for people that don't know the tribe, and also gets easier to find later.
I'm glad we are talking about this, the sooner we can find a tag to call our own, the better this tribe will become.
Thanks for bringing this topic up!
Keep posting and keep shining!
