I think the technophobe/luddite one would make sense for an off-the-grid type Sim.
I would like a trait that is somewhat in between Loner and regular social sims. I know there is a reward trait called "independent" but I want my Sim to enjoy social interactions when they happen & not be totally uncomfortable around other sims but to not constantly crave social interaction & to be able to maintain friends by interacting with them online & via phone instead of in person. Not quite an introvert but not quite social either. The Independent trait reward is nice, but it doesn't seem to stop social embarrassment/tenseness from being around other Sims. I'm ok with a Sim being uncomfortable in a party setting with a lot of strangers, but they should be more comfortable if surrounded by friends. I hope that makes sense.
A trait for Sims who are in to super high-tech stuff would be great too (do we already have a technology buff type one?). These Sims love any type of tech and excel at using it & do things with tech faster. In line with this, I would like these sims to do their reading digitally instead of with paper books. I have found that as I've gotten older & my vision has gotten worse, it is easier for me to read from computer screens than from books and magazines in paper form.
