alt Hacker NewsFor my company, being able to view the user journey throughout the site in the analytics is pretty valuable.
We don't care who the specific users are - but the tracking gives us an idea of how many people use the site? do they have a good experience? are they giving us money? do we have a bug somewhere we're missing? etc.
All that is valuable as a business.
Back in the day we used to track user activity via a "hit id" (basically a random string) that was generated on the backend that added a "post" request to every page.
Idk if that was a good idea or not.
