What topic do you LOVE to talk about, but rarely get to?
Everyone has something they can't stop themselves from nerding out over - but often it's hard to find people to talk to about it. So go ahead, share your interests, and tell us about them!
Linguistics/languages. It's what I majored in. Unfortunately, being a linguist on the Internet is a Sisyphean task—when you point out that language changes and doesn't always mean what you think it should mean, people get upset.
Related to the above, conlangs (constructed languages—e.g. Klingon, anything Tolkien, Sangheili (sp?) from Halo, Na'vi). It's a very niche hobby.
My Little Pony. I am a dude. I like the wholesomeness; it's a break from everything else being gritty and dark.
Music theory. Like, deep music theory. Meshuggah counting? Microtones? Obscure composers and releases? I love that shit.
Yes! And I've also looked into Indian counting patterns (e.g., Sarah Thawer, the drummer, from whom I learned about the rupak taal). My favorite composer is Philip Glass and minimalism as a genre owes a lot to his experiences with Indian music. Unfortunately I got into Glass when I was in high school and nobody else gave a shit.
Since you're mentioning both linguistics and music theory - did you know that the music of Avatar was originally supposed to be completely different, essentially an alien counterpart to tribal music? I'd love to hear what they started producing, but afaik nothing was ever released. Still, there are some interesting videos on this topic!
