Personally, I prefer literate Rps. I have been with stuck-up literate role players, but if the Rp I'm in is strict , I can usually avoid meeting those people. If I'm seriously role playing, I can only Rp with literate people, since I can't stand the simple style that would be like '*runs away*' (Plus I'm a grammar nazi, so I get annoyed by people's grammar mistakes xD). On the other hand, if I'm not seriously Rping (like just derping around o3o), then, obviously, I use the simpler Rp style. :3
But, yeah, that's just me. ouo
