Sometimes the world can seem like a pretty scary place. Other times, just the sheer volume of information is enough to make people resist casually searching for things or ideas. After all, most sites are unwaveringly aggressive in throwing words and provocative images at you, while other times things get lost in the deluge of “breaking news.”
