True but that still publishes your content to nostr in a native way instead of driving traffic away. 

There is also content indexing from search engines. Publishing content to nostr first (as an alleged Nostrich or Bitcoiner) will give the app or site you're using the search ranking. Publishing elsewhere first to then publish the same thing later on nostr is deemed duplicate content and it will get strikes by the engines.

Just another thing to consider as "nostr creator".
