A brief, related rant:

Why the heck do mobile browsers not implement any sort of full page zoom or viewport resizing? (Perhaps better called "page scaling"; it's what desktop browsers do when you press control-plus/control-minus.)

My choice is either to increase the browser's text scaling and deal with tiny UI elements (e.g., upvote/downvote buttons on HN), or pinch-zoom and pan around. Both are awful.

All the machinery for full-page zoom ("page scaling") is already in the browser! Just let me use it!
