I feel (because it's a feeling) that HN stays good because it lacks images in the discussion area. The clean look, no adds, limited everything really proves the case that less is more.
A large organic hass avocado is between $2 and $4. You need at least half of one to make good avocado toast. If the loaf of bread cost you $5, and makes 20 slices, that's a base cost of $2.25.
