In the world of Hai:Probably just a "polish" issue but I feel like the "Write Post" interface should be on world views and should default to that world.
That said, I was trying to think of a world to post something to and having trouble picking.
If I want to talk about the Guardians of the Galaxy movie do I put it in the "Marvel" world, the "Movie" world, the "Marvel Cinematic Universe" world or the "Comics and Genre Fiction" world.
What would be nice, I think, would be for there to be something like "nesting" but in a way that allows a post to exist in multiple worlds.
So the "Marvel" world would fit into the "Comics" and "Genre Fiction" worlds and the "Marvel Cinematic Universe" would fit into the "Marvel" and "Movie" worlds... and if I subscribe to a "parent" world I would see posts from it's "children".
It might just be easier once there are more existing worlds to play with.
