W-o-W!!! Thanks so much for these links!
I just stumbled upon lesswrong.com while searching for information on Zettelkasten and I must say this site is STUNNING! This is some of the most beautiful typography I've seen, anywhere! The attention to detail is exquisite! I haven't even gotten to your content yet! This will probably remain a permanently open tab in my browser... it's a work of art!
