So, here I am messing (again) with the blog fonts, wondering about sans versus serif and legibility and look. There are so many clients now, and different resolutions, that it's hard to take them all into account.
I was using a Google web font called PT. Now I've actually switched to basic Times New Roman and feel like I'm some sort of web neanderthal! But playing with CSS (size, height etc.) makes it seem very clear and legible to me. Let me know if not.
