+A thread is a `kind 11` event.  Threads SHOULD include a `subject` with a summary
+of the thread's topic.

+```json

+  "content": "Good morning",

+Replies to `kind 11` MUST use [NIP-22](./22.md) `kind 1111` comments. Replies should
+always be to the root `kind 11` to avoid arbitrarily nested reply hierarchies.
