Ask HN: Zooming on HN on Android phone?

I am really struggling to see the microscopic type when reading HN comments on my new phone.

On my old Galaxy Nexus (Android 4.3), using the Android Browser, I could zoom to get the size type that I wanted, then double-tap to get the text to wrap to my screen's width.

On my new Nexus 5 (Android 4.4.2), this doesn't work. Double-tapping makes it zoom out again.

Chrome doesn't do it on either phone. I prefer to get this working on one of these two main browsers, but I could try some others.

Any ideas?
