Pinterest

Pinterest is the canonical masonry layout: a grid of variable-height image tiles that stagger to remove gaps, scrolling forever. It made discovery feel like rummaging rather than searching. Tapping a Pin opens it without leaving the flow, and closely related images cascade directly beneath, turning every item into a fresh jumping-off point. Saving to boards is the core verb, and the act of organizing what you find is itself the product. Visual search lets you crop part of an image and find lookalikes, which suits a catalog of objects over text. The interface leans almost entirely on the picture, so weak or text-heavy Pins read poorly in the grid, and the relentless related-content cascade can pull you sideways far from your original intent.
