Every time someone says a website should update their look people think they mean it should look like Medium and be brigaded by design school freshmen who'll make the page weigh 900gb.

I don't know what the original commenter meant, but the text could be a bit bigger and the line lengths and spacing controlled.

The comment metadata could be shortened and humanized, though the audience may find it useful.

There's some bugs with the dropdowns on mobile (haven't been able to close one).

I don't know if that will get them subscriptions, but it'd make the site easier to read.
