> "humans would visit the website and the creator would get some reward"
That expectation is a problem, has always been a problem, and Tim Berners Lee never mentioned anything about a reward structure when coming up with the WWW.
Did the operators of HN mention anything about a reward structure for posting comments here? I'm sure you can see how that's still attractive to some.
Your thinking too narrowly about the reward. Sometimes, it's just about the getting the knowledge out there that's motivating the creator, not anything tangible for themselves.
