Gradation
This is a journalism site for community posts regarding movies, anime, video games, and pop culture in general. They use a fair amount of gradation throughout their branding, which I do enjoy, a nice fade from a warm purple to a deep pink. Their consistent use of these colors, the fonts and the brand identity work very well here.
Simplicity
Reddit is a hub for communities and conversations on thousands of topics and concepts, and while it has a vast user base and list of subcommunities, it still embodies the concept of simplicity. The home page is very straightforward and doesn’t use any unnecessary flourish- it shows you the set of menus, the topics, what’s trending, and the resources. The only part that moves on the homepage is the part that contains the latest feed.
