Global Space could have every single post (of all the groups you have click 'join') but we could also have different groups to post in order for the people that only watch certain types of drama and don't want to see posts about everything.
For example, someone wants to post about a K-drama so they post it in K-drama Space. The post appears both in K-drama Space and in Global Space but not in C-drama Space.
Also, same concept as there is right now about joining a group if you want content about K-dramas and J-dramas but not about C-drama, for example. You don't join that group. So that in your Global Space you have posts about K-dramas and J-dramas but not C-dramas.
Just an idea :)
