I humbly submit my own blog as being pretty darn readable without bloat. It’s responsive and simple. https://alanhogan.com
Edit: Here’s a relevant article: The problem with new blogging platforms https://alanhogan.com/the-problem-with-new-blog-platforms
Firstly, I hate sites that use such a narrow column on the screen. The wall of text from the previous post is obviously too much and is far too difficult to read and keep track of where you are, but using only a third of the screen seem far too little. I'm sure you could double the width of your text without affecting readability.
Secondly, I have really good distance vision but need reading glasses. I find the text on your site a bit small. From a distance it just a bit too small to read comfortably and from close with my reading glasses I feel like I need to get too close. Yes, I can increase the font size easily, but how about...
My suggestion: decrease the size of your borders by about 50% on each side and then increase the font size by 1 or 2 points. The increased column size will give more text on screen, but the increased font size will make sure it is not too much.
FWIW most professional typographers recommend a column width of 30-40em. Much more than that seriously increases the distance the eye has to travel from the end of one line to the beginning of the next, and makes it harder to keep track of where you are.
The max-width of this blog's main column is... 40em.
And now you know why so many sites do this thing you hate.
(An em, if you are not familiar with it, is a typographical measurement equal to "the width of an M in this font".)
Far be it from me to argue with professional typographers, but do you hear anyone saying "oh, the line lengths on paperbacks are far too long, I can't scan them"?
Maybe it's just me but I'm a little tired of always having to cater the the very lowest common denominator. That narrow width seems almost ludicrously too narrow to me, it's like a childrens book.
There has been research that suggests that most people don't finish articles, so it seems to me that maybe making columns so narrow is catering to the audience most likely to have such a short attention span that they probably won't finish your article anyway.
Or maybe I'm just a moany old git :-)
If most websites were like this one, I could write a simple one-page CSS that formatted them the way I want - including fonts, colors, lines etc. As originally intended by this whole HTML thing.
Cheers, Alan.
