im studying graphic design so i feel this question in my soul.
my first instinct is to say BODONI, it's beautiful, historical, it just tickles my brain in a way. but it's not the most versatile. it has a certain vibe to it (which i love)
FRAUNCES has the same problem, but this time it's a modern typeface inspired by vintage calligraphy. it has a bunch of variants and can look wildly different...
but for mor readable fonts i adore MONTSERRAT (argentinian bias) and ATKISTON HYPERLEGIBLE. the last one i use everywhere i can, it just makes it much easier for me to read... i use it on my site, my blog...anywehere i can. also i think it looks cute
