It sounds like a good idea, then I do not need to subscribe to a Non-Fiction writing site and a fiction writing site, and a sci-fi site, steam-punk site, ect. One site to hold all. 

The arts and crafts community also have a lot of different arts and crafts from tie-dye t-shirts to crochet and knitting. the easier a community is able to make finding content for the casual user the better. There are a lot of other ones also, like sports, and photography, and likely ones I don't see on a daily basis.

not a bad idea. we will see that problem mostly in "general" communities, but sub-communities would be nice addon.

i am not sure even how 3Speak community works. i think it is not automatic to post there when you post on 3Speak. is it a double post, or maybe just adding a hive-100421 tag?

Hi @midlet

where could I find "sub-community" button?

I love everything about this idea.

I'm not really sure if people want to create their community under certain parent community. Speaking about ownership and authority, and... ego.... Looks like at current state, communities in steem are designed to be more like facebook groups (which is fine, since some of successful facebook group do have high engagements in their contents).

It's a good idea. The way to do this would have to be for the main community to specify in a custom json broadcast what it's subs are. That way it would be able to pull subs in that aren't necessarily owned by it. However, that could create a scenario where someone adds a sub that shouldn't be a sub, misrepresenting ti.

That would be a fun extension to communities.

So there's a couple ways to sub organize a community. 
1. Let the community detail (community settings... aka metadata) which TAGS they'd like to use to subdivide posts. 
Not sure how well hivemind handles this but i'm guessing it will be just fine. 
This provides pretty much ONLY a subdivisions of content but also does kind of let users know which kinds of content is popular and expected. 
2. Have multiple hive communities tied together and Let a community state which community is a PARENT community. 
They would be legit communities each one of them ... this allows different moderators, labels, descriptions and allows people to SUBSCRIBE to different sections of a large community structure. The interfaces would be expected to list the child-communities and the child community the parent one. However the issue is letting people know they may not have child-community content show up in their feed unless they specifically subscribe. 
3. I suppose a mix of the two could be good. 
Meaning only tie multiple hive communities together if there is a reason to have varient leadership moderators and maybe subscribers. For example a POSTING community and a FORUM type community maybe a 3rd option could be a community that is for OFFICIAL POSTS and is more of a locked community that only the organization/business can post to. People can subscribe to that one as more of an Important feeds sort of thing. 
Otherwise divide by topic/keyword. 

Thoughts on that?

I support this simple but brilliant idea!

Yes, this is what I'd like to do! I was trying to explain it to @crimsonclad in Dm, but couldn't explain it properly. From a @naturalmedicine perspective, we'd have 'herbalism' 'yoga' and so on.

Cool idea 👍Another way to implement this could be 'parent communities' -- i.e. a container which holds multiple communities. When you subscribe to the parent community, you are automatically subscribed to all the children.

I think that is a magical idea.

I also think past a certain point (maybe three tiers?) it would have to be optional (at least for posting, give me all the tools to explore an entire rabbit labyrinth when browsing though!) otherwise it would drive people (or at least me XD) mad.

Yes, it probably will be needed. Maybe, communities have their own tags?
