Assuming you’re sincere :) The same text in different fonts, or different type setting with the same font, absolutely does convey different meaning. Most simply, UPPERCASE IS SHOUTING.

Letterforms make a huge difference to how text is read, perceived, and remembered, and how much it affects us. Unless you’re a wild outlier in some way, you are affected by type treatments.

I don’t know if you can visualize it, but I clearly can: the word “Daisy” set in (a) an elaborate script font, (b) a blocky slab sans-serif, (c) child-like hand-drawn letters. Most people will assign different meanings to each, and many people will derive more meaning from the type than from the word.

Do you have a child? Would you recognize their hand writing? Same thing.

I am sincere. You've picked some pretty obvious differences. I'm talking about the vast majority of fonts which are to all intents and purposes identical. I don't know if you have a kindle but to restate my original question - if you read the same book using each of the 8 or so built-in fonts, do you seriously believe you are reading 8 different books? I'm sorry, it's just a nonsense. Sure, you can have a favourite font or dislike how..i dunno..descending letters look, but I simply don't believe normal human beings look at a (normal, not comic-sans etc) font and a) give a shit about it, and 2) feel that one is more "professional" or "zippy" or some other adjective, like a designer has reached into their soul.

In this particular instance I disagree. The default Office font is the font that many people will read/write a very significant portion of the text they consume/produce in. So it’s nice if it’s a decent font.

I totally agree though when it comes to longreads of some over funded startup that redesigned their “brand identity” and commissioned some custom “fun, quirky but still authoritative and inclusive” font. That is just designers cirkcle-wanking.
