I have a weird obsession with fonts. I love a good, well designed font. How it looks on the screen, how it looks in print. Nothing too gaudy or showy, but a really good League Spartan or Lato Light. (Not a fan of serifs)
Other than that, normal stuff; 3D modelling, writing, etc...
My other interest that might fall "outside the norm" is that in University, if I had continued beyond my bachelors my primary focus would have been studying the Bronze Age Collapse, and that topic still fascinates me to this day.
Edit: Oh...and spreadsheets. There's no problem in the world that can't be fixed with a well designed spreadsheet. All problems come down to data sorting.
Spartan is a bit wide for me (see that w?) but Lato with a good colorscheme is always sexy
Another thing: if you're familiar with fonts you can have a weird pseudo-Sherlock funtime guessing how something was made.
points This book is using Georgia instead of Times New Roman. See how the 9 is low? But the page numbers are Times New Roman because the 9 isn't low. Was paging in the author's control?

font with the light blue shading thing. This club recruitment poster was made in Microsoft Word.
About serif disdain... what about LaTeX's serif? :}
If you're into Computer Modern, almost all modern tech variants (not Knuths original) are too light in print. If you look at his printed books from back in the day the letters are thicker. It's just a consequence of using one technology instead of the printing tech the font was designed for. Same thing (but more extreme) happened to Centaur btw.

I like Noto Sans. But as a Linux user it often irks me too, since every....single...language...is included in most distributions; so half of my time finding a nice font that I just installed consists of scrolling past a bajillion Noto variants.
I have almost no opinions on specific fonts. Except… I absolutely despise the $ and ¢ symbols in Apple's San Francisco font. Since it's the default font I have to look at it a lot.
