 ### Kind: 30011
 
-Link list events use kind `30011`.
+Link list events use kind `30011`. This number was chosen because:
+1. The "11" in 30011 visually resembles "ll" for "link list"
+2. It falls within the addressable event range (30000-39999) as defined in NIP-01
+3. Maintains separation from other list-type events (30000-30009)
+4. Avoids conflict with previously used kind numbers
+
+As an addressable event (NIP-01), for each combination of `kind`, `pubkey`, and `d` tag value, only the latest event will be stored by relays, allowing for efficient updates to link lists.
