Elon admits to link throttling on X. In response to Paul Graham's complaint about X deprioritizing links, Elon suggested a workaround, inadvertently confirming that posting links on X is a surefire way to kill your engagement.
Just write a description in the main post and put the link in the reply. This just stops lazy linking.
The consequence is that people still post links, but just more deceptively. Which PG points out in the replies:
The actual reason for the throttling is that X takes a revenue hit when users click away from the platform.
