Keep in mind that people who apply serious life-changing ideas after reading about them in fiction are the exception rather than the norm. Most people who aren't exceptionally intellect-oriented need to personally encounter someone who "has something" that they themselves wish they had, and then have some reason to think that they can imitate them in that respect. Fiction just isn't it, except possibly in some indirect ways. Rationalist communities competing in the "real-world" arena of people living lives that other people want to and can emulate are a radically more effective angle for people who don't identify strongly with their intellectual characteristics.
