Use cases ideas Edit
Use case 1: UserA shares a deck
Use case 2: UserB starts using a shared deck
Use case 3: UserB corrects a mistake
Use case 4: UserA benefits from a correction
Use case 5: UserC "forks" a deck to bring it in a different direction which is incompatible with what other users need (for instance switching explanations from English to Polish)
Should each deck sharer maintain "ownership" on it?
Should the fork feature be very prominent (like on Github)?
How should corrections work?
Being able to comment on changes would probably help.
First on AnkiDroid only?
First on a web UI only?
