My chosen subject was physics. It's quite common to find that physics undergrads actually want to know physics; that it's not simply a planned stepping stone to some future job. I followed up with a masters in it, and several years later did another masters, in maths, at my own expense in evenings and weekends, with the same motivation; I had been doing some mathematics, and was annoyed at how bad I was at it, and decided a masters in maths would sharpen that right up.
People like me exist. We are real. We exist in the blind spots of your world, taking genuine interest in things. Learning for no other reason than that we simply want to know more. To understand more. To have a fluidity with more knowledge, more understanding. You just haven't noticed. We don't have a manifesto or a webpage because we've got more interesting things to do.
