Top Programming Fonts
From my experience,a lot programmers get set in their ways. For example, I just stuck with using the standard Console font for my IDE when I installed it years ago.
Then I came across this article, or one similar, and messed around with different fonts and sizes. The difference it made was surprising. I feel like it definitely has made an improvement in how I work.
I would recommend people try testing new fonts, layouts, etc at least once a year. the aesthetics is just as important as the content, even when coding.
