Welcome, flyergrad!
It's great to have a new fellow-fan. As you guessed, just because you don't see an author discussed here doesn't mean we don't like him/her. A lot was lost when the old SeniorNet site imploded. I think we did talk about Herbert there. I haven't read him, but a daughter, an economist says I have to read him for the economic system.
A lot of us are Harry Potter fans. Those books stand up well to rereading. I read the first 4 aloud to my husband when he was too sick to read stuff for himself, and when I wanted to review my Spanish I read El Prisionero de Azkaban and half of El Caliz de Fuego. You're right, the movies don't capture the incredible richness of ingenious detail in the books, and they mess about with the plots in an unfortunate way.
A lot of us also like Terry Pratchett. If you haven't tried him, you might have a look. The books vary a lot in quality, though.
I do still own several slide rules, though I haven't used them for half a lifetime. They are actually better than calculators for a few things, but I can just imagine the laughter if I pulled one out.
Just because you don't see something here doesn't mean we don't like it. Tell us your favorites, and you'll probably hit paydirt.
You're right about taking Latin. Everyone I know who has taken it is glad they did. Come talk to us whenever Ginny gives you a free moment.
