I worked with a marketing team at my last job that helped us navigate some fonts that were easy to read and universally used. I have also created some brochures and marketing publications in previous jobs that gave me some experience with different fonts that I thought about when creating my font for the blog.
I used the medium setting so that it would be easier to read and I liked how the letters were spaced apart from each other. I liked that the font was a serif font since I prefer serif and the blog is not meant for children and that some blog posts could be lengthy. I kept the black font color because it is the easiest to read however when highlighting a a phrase or title, I might use a color font.
