This was an idea that came to me last night and I figured out this morning: how to tell a story on Pinterest. For content such as comics, DIY books, or instructions this could potentially be a game-changer.
That was the case with the last Pinterest popularity algorithm. It was of elegant and fair design that prevented spam as well as promoted new content. Probably the most important factor in the old algorithm was the chance for ANY user to show up at the top of a specific category page. This is vital because it gave regular users a chance to have their unique content promoted and seen before thousands of eyes.
