It looks nice. When everyrhing consistently looks nice, thise small things accumulate into one apple.

In my e-reader I changed the font to Roboto Mono and completely forgot it was monospace. It's not like reading feels any less efficient. Idk might even feel more efficient or comfy somehow.

Maybe there's an advantage to having each successive character appear perfectly rhythmically across the page.

What I want are two or even three shades for consecutive lines, to make it easier to transition from the end of the current line to the beginning of the next.

Hmm can you explain? Would that be like line 1 starts out purple, transitions to light purple at the end of the line, and 2nd line starts light purple, transitions to pink, 3rd line starts pink and transitions to purple?

Kerning lets letters be spaced more uniformly, which is easier to read for most of us.

It also allows letters to crowd each other like friends in a wacky group photo, a tree overhanging a sidewalk, or a cat's tail doing its weird contortions. Fonts are fun.

It’s worth the trouble I think, but there are options if you’d rather not support it.

it's one of many little things that add up to "oh your poster looks much nicer than the others" - but they can't put their finger on what exactly makes it nice.

The costs aren't enormous or anything close to it.
