Sounds like an authentic HN experience to me!

I whipped up a quick uBO rule to fix that (also makes meta-information lines readable):

    thefrontpage.dev##p.newspaper-copy:style(line-height: normal !important; font-size: 1rem !important;)
    thefrontpage.dev##p.article-meta:style(font-size: 1rem !important; font-weight: normal !important; letter-spacing: normal !important;)

OP, I love the font size as is, have multiple options if you're going to change things! Remember the users that loved things as they were!

I agree, but I think it's that small because otherwise, the justified text results in ridiculous spacing.

OP, consider reducing the number of columns from 4 to 3 (at least below very wide viewports), increasing the font size, and then also allowing hyphenation. I think the last will help a lot with the justification problem.

An overridden `.newspaper-copy { font-size: 1rem; }` works well.
