- zoom into the button, then click
- override the css yourself, e.g,: using your one of the many userstyles extensions or browser developer tools
- inject custom JavaScript using GreaseMonkey or Tampermonkey
- use a third party HN client. As you would imagine, there's a sea of those - one of them must be halfways decent :-D
- purchase a new device with better touch precision. Pixel 3/6 with display scaled down handles the problem of adjacent links smaller than a fingertip exceptionally well
- If able, try to reduce the finger sausages. Otherwise, use a stylus.
Why should YC change it for everyone to make it more attractive on your device?
