Public addressing

Public addressing is discussed here. The essential point here is that Public, as:Public, and https://www.w3.org/ns/activitystreams#Public are equivalent as JSON-LD and thus should be treated in the same way by Fediverse applications.

Examples

Example 1

```json title="activity"
{
  "@context": [
    "https://www.w3.org/ns/activitystreams",
    {
      "Hashtag": "as:Hashtag",
      "sensitive": "as:sensitive"
    }
  ],
  "type": "Create",
  "actor": "http://pasture_one_actor/actor",
  "to": [
    "http://bovine/endpoints/cCymvw_8wcviEwAgrvkkb23N6OGZlQ6wMW9bWKqWBYM",
    "https://www.w3.org/ns/activitystreams#Public"
