### Security
Designing for public communication requires less focus on privacy than more intimate social applications. However, privacy for user metadata is still important, and private direct messaging is a feature that may need to be supported.

### Access Control
There may be a need for different levels of access to user data - for example, to create read-only applications, paywall, or private sharing.
