Nice webapp! One small improvement that would make it more usable for me would be not to limit titles to a single line on the homepage - it would be a more smooth experience if I could read the full title before clicking it. Thank you.
I should add that the reason the title text is currently overwrapping to ellipsis on phone screen instead of breaking words into new line is because the meta tags aren't relative to the title. HN seems to be using tables to avoid this issue, I might do the same or use flexbox instead.
