Kern your punctuation. Please and thank you.

Tiffany Wardle

First, I acknowledge that kerning is not always needed. For examples, monospace or Trinité both do not need/have kerning. 

Second, I have never designed a typeface. I have only ever reviewed and used them. So I make certain assumptions when a typeface is being made that the designer does the spacing first, then kerns, then finds things to improve, ad infinitum until they release the typeface. In other words, I like to give people credit for following best practices.

Third, I know nothing and want to know more. ¯\_(ツ)_/¯

All of this said, as I review typefaces I am amazed at how often I'm displeased with the kerning of pairs which include punctuation. I often start with looking at @Christoph Koeberlin’s useful http://typefacts.com/kerningtest paragraph. I find that it shows plenty of flaws to make general comments. Even within the first sentence I'm sometimes/often/frequently (but not always) dismayed at the lack of attention to detail in kerning such pairs as /“A/ /f”/ /‘A/ /f’/ and /’./

Am I expecting too much?

Edit/Note: I also realize it is very subjective. I'm not the sort to tinker when I'm doing my work unless absolutely necessary. That is where my original tweet started. I was exasperated to see I needed to tweak.

Punctualion is frequently ignored on favor of thousand of pairs between lowercase letters. 

The default kerning strings in Glyphs.app have those pairs.

I would even dare to take it a step further. A lot of typeface have bad spacing. Spacing should be incorporated into the design form the very beginning. It is the backbone of your design. It defines rhythm, proportion, color and flow. There is a tendency of spacing a collection of forms, without really looking at the design and its needs. I prefer a well spaced typeface without kerning than a bad one with.
