This characteristic that the label of the community must be placed first and that only works if it is there, severely limits the possibilities of spreading the posts.

It's the same for every other Platform (GAB, Minds, MeWe) which has groups or communities.

MeWe solves that by allowing to specify a group when re sharing. GAB and Minds only allow to reshare a group posting into your own Profile. All three allow to add comments to reshares.

Steem are the most primitive. Only reshare into the own profile and without even a comment.

I think the MeWe approach, allowing reshares into groups with optional comments, is the best.
