Eh, I think they care about Enthusiasts more then we think. Few people are willing to travel for this stuff, and enthusiasts usually purchase souvenirs or some crap. It's a guaranteed audience. Obviously, they're main focal point is the GP, as that's where the money is, but they're designing a roller coaster that both enthusiasts, and the GP will like, so, why not?
Think of it like the music industry. Take something like Judas Priest, for example. If you don't know anything about music, it's just good (or bad) music to you. To us musicians, we can tell when they throw in little stuff that both the players, and musicians, will enjoy and notice. For example, maybe during a solo, the guitarist or vocalist, goes into triplets, which isn't really that complicated, but this is judas priest. The rest of the band is still in straight 8th's or whatever. To those of you reading, you have no idea, you just hear music. But to us musicians, we know what's going on and we follow. After all, musicians are more likely to buy a limited edition CD or something. So, you're already catering to the GP. You're making something both enthusiast and GP will enjoy, why not add a pop here and there for the musician? Kill two birds with one stone.
I mean, the GP enjoy hangtime, ejector, floater, lats, everything we do, they just don't know. Music is slightly different, as I like to play stuff in irrational meters like 19 over 15/16 polyrhythm into 37/19 or something, which isn't necessarily the general person's idea of good music, because they're uneducated. Coasters are more straight forward.
