FWIW, you can login to here (https://news.ycombinator.com) using eww. The only minor issue is you are really limited to 1 line if you want to comment. And seems you cannot vote either.

I have yet to figure out how to get around those issues.

And a big plus, eww is great for resource limited systems like old 32bit laptops.

1 line? Did you try C-q RET?
