So you’re intentionally exaggerating when you say “nothing has changed”. Yeah nothing has changed, except an entire Executive Branch department that didn’t exist before. It was more influential than many other books written at the time.
Of course the author wanted the book to be even more influential, that’s why authors write. No writer says “this book kinda sucks, I hope people read half of it and put it down”.
That’s putting it a bit strongly. But it does induce people to spend money. Personally I don’t spend extra money on games. I can go to Vegas if I want to gamble for money.
That’s because posts are not just thoughts in your head. You are selecting the particular thought you want to publish on here. You are promoting it.
Very few people are “just saying” or “just asking questions”. Usually those are just rhetorical devices for introducing unpopular ideas that would be rejected otherwise.
Apple releases “iTetris” for $3000. Their fans claim it’s way better than the original. It’s the same game with only 8 levels, but you can pay extra for more.
