+A reaction is a `kind 7` event that is used to indicate user reactions to other events. A
+reaction's `content` field MUST include user-generated-content indicating the value of the
+reaction (conventionally `+`, `-`, or an emoji).
 
-The generic reaction, represented by the `content` set to a `+` string, SHOULD

+A reaction with `content` set to `+` or an empty string MUST be interpreted as a "like" or "upvote".
+A reaction with `content` set to `-` MUST be interpreted as a "dislike" or "downvote".
 
-A reaction with `content` set to `-` SHOULD be interpreted as a "dislike" or
-"downvote". It SHOULD NOT be counted as a "like", and MAY be displayed as a
-downvote or dislike on a post. A client MAY also choose to tally likes against
-dislikes in a reddit-like system of upvotes and downvotes, or display them as
-separate tallies.

-The `content` MAY be an emoji, or [NIP-30](30.md) custom emoji in this case it MAY be interpreted as a "like" or "dislike",
-or the client MAY display this emoji reaction on the post. If the `content` is an empty string then the client should
-consider it a "+".

 There MUST be always an `e` tag set to the `id` of the event that is being reacted to. The `e` tag SHOULD include a relay hint pointing to a relay where the event being reacted to can be found. If a client decides to include other `e`, which not recommended, the target event `id` should be last of the `e` tags.
 
-The SHOULD be a `p` tag set to the `pubkey` of the event being reacted to. If a client decides to include other `p` tags, which not recommended, the target event `pubkey` should be last the `p` tags.
+There SHOULD be a `p` tag set to the `pubkey` of the event being reacted to. If a client decides to include other `p` tags, which not recommended, the target event `pubkey` should be last the `p` tags.
 
 If the event being reacted to is an addressable event, an `a` SHOULD be included together with the `e` tag, it must be set to the coordinates (`kind:pubkey:d-tag`) of the event being reacted to.
 
-The reaction SHOULD include a `k` tag with the stringified kind number of the reacted event as its value.
+The `e` and `a` tags SHOULD include relay and pubkey hints. The `p` tags SHOULD include relay hints.

-Reactions to a website
+External Content Reactions
 ---------------------
 
-If the target of the reaction is a website, the reaction MUST be a `kind 17` event and MUST include an `r` tag with the website's URL.
+If the target of a reaction is not a native nostr event, the reaction MUST be a `kind 17` event and MUST include [NIP-73](73.md) external content `k` + `i` tags to properly reference the content.
 
+_Reacting to a website:_
 ```jsonc
 {
   "kind": 17,
   "content": "⭐",
   "tags": [
-    ["r", "https://example.com/"]
+    ["k", "web"],
+    ["i", "https://example.com"]
   ],
-  // other fields...
 }
 ```
 
-URLs SHOULD be [normalized](https://datatracker.ietf.org/doc/html/rfc3986#section-6), so that reactions to the same website are not omitted from queries.
-A fragment MAY be attached to the URL, to react to a section of the page.
-It should be noted that a URL with a fragment is not considered to be the same URL as the original.
+_Reacting to a podcast episode:_
