If everyone stops reading outside of HN, we won’t have HN posts to begin with. So YES, not everyone should stop reading outside HN.

This argument only works in the limiting case. If 1% of HN readers read outside HN and post the good stuff here, that would keep the front page well stocked.

Well stocked with what that 1% like and appreciate, so we'd need for that 1% to be representative of the whole, otherwise users will leave until it becomes representative enough. But hey, that's a wild guess
