/**
* The identity manager takes care of loading and storing identities, their
* contexts, and properties. It does so in a way that does not expose errors via
* exceptions but it only logs them and tries to return sensible defaults.
* <p>
* It is also responsible for polling identities from the Web of Trust plugin
- * and notifying registered {@link IdentityListener}s when {@link Identity}s and
+ * and sending events to the {@link EventBus} when {@link Identity}s and
* {@link OwnIdentity}s are discovered or disappearing.
