this is only tangentially related to the article, but I've always found text justification strange. For me paragraphs with ragged edges are easier to read than justified paragraphs, because the irregular ending point helps me keep track of where I am. And justification can lead to some very odd-looking lines. So I've just never quite understood why it's so common in typesetting

I've never given this much thought, but I agree with you 100%.

After reading this article I thought "wow that's really impressive and I hate it".

For the same reasons you mention, and the words seem to "blend together" into a blob of text and losing my interest.

Still super impressive that people do this though.

Same here, justified text feels difficult to read. And, I had academia where where students are forced to justify text....
