-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:_
+```jsonc
+{
+  "kind": 17,
+  "content": "+",
+  "tags": [
+    ["k", "podcast:guid"],
+    ["i", "podcast:guid:917393e3-1b1e-5cef-ace4-edaa54e1f810", "https://fountain.fm/show/QRT0l2EfrKXNGDlRrmjL"],
+    ["k", "podcast:item:guid"],
