Hermit: a font for programmers, by a programmer

For instance, I prefer Menlo font and find it much better looking than Hermit.

Including the comment I was about to type before I realized it had already been written:

"I hate to say this, but a font by a programmer makes as much sense as a database library by a font designer. Good font design is not about calculations or following principled rules; it's about what looks good to the eye, and it takes a tremendous amount of skill and experience. And to my eye, at least, the font is incredibly difficult to read. It literally looks like a font designed by an engineer for a plotter, not something designed for the human eye or legibility. Good fonts follow intuitive rhythms, they focus on word shapes (not just letter shapes), natural curves, there's a tremendous amount of subtlety that goes into achieving a proper sense of balance between letterforms, and a lot of things are actually different between letters/curves/etc. so that they look the same to the eye in the end. Even with "utilitarian" fonts like monospace ones. "Carefully planned and calculated" is a great recipe for building a bridge, but not for building a font, unfortunately."

If you haven't seen it yet, Fantasque Sans Mono (formerly Cosmic Sans Neue) is my current favourite. It's worth checking out. http://openfontlibrary.org/en/font/fantasque-sans-mono
