Nerdfighteria

Nerdfighteria (nerd- ) is a mainly online-based community subculture that originated on YouTube in 2007, when the VlogBrothers (brothers John and Hank Green) rose to prominence in the YouTube community. Nerdfighteria, whose followers are individually known as Nerdfighters, grew with their popularity. The term was coined when John misread the title of the arcade gameAero Fighters as Nerd Fighters.

Hank Green describes it as "a community that [sprang] up around our videos, and basically we just get together and try to do awesome things and have a good time and fight against world suck," which he defines as "the amount of suck in the world". The Greens established The Foundation to Decrease World Suck in order to raise funds and launch projects that would help a variety of causes. Nerdfighters believe in fighting world suck, promoting education, freedom of speech, and the use of the intellect in modern society. Nerdfighters and the Green brothers have collaborated on many projects such as the annual charity fundraiser Project for Awesome and the digital media convention VidCon. The Nerdfighters have been described by The Hollywood Reporter and The Wall Street Journal, with participants estimated to be 100,000 in 2014.
