This is a really great video from Hoefler & Co. on the making of Operator, their newest font, available in monospaced and what they call "monspace-inspired" versions. I use Hoefler fonts on this site (Quarto, Gotham, and Decimal) and I love them.

So with designers, developers, and most of all readers in mind, we decided to design it both ways. Operator Mono is our new family of fixed-width typefaces, with a broader range of weights than a typical typewriter face, and an italic that positively shines in code. Its more editorial companion is the natural-width Operator family, which offers the voice of typewriting but none of the compromises.
