That is actually wrong. It is dangerous to create world-writable files and share them between users. If you need to share data between users that is not fixed (e.g. it would make sense if Apple installed GarageBand loops in /Application Support, as they will be used by all users that launch Garage Band, but since Garage Band comes preinstalled you don't want all that disk space for the loops to be used, you want to download them later). If you have databases shared by multiple users, you should use a Launch Agent plist that launches a server process, then have any instances of your app currently running (remember, there may be multiple instances running under Fast User Switching) talk to that process. That way, the process can also enforce valid file formats, making sure one user can not ruin things for another user by feeding invalid data or deleting their data.
