While Reddit is often compared to Digg, the two sites have some key differences. Reddit has a simple interface and little advertising. Many users love this simplicity.
Reddit rankings are based on an absolute vote (+1 for hot, -1 for cold), meaning a story can dance up and down Reddit’s top page instead of being buried out of existence by a few power users. To see what’s on top now, there’s also a “hot” list. This type of voting system also means the front page can be stagnant, to the chagrin of some users, but it has also avoided Digg’s payola scandals. Another big differentiator for Reddit is their recommended article page, which suggests links based on your voting pattern.
