[4] Hank Green describes it as "a community that sprung 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".
[5] The Greens established The Foundation to Decrease World Suck in order to raise funds and launch projects that would help a variety of causes.
[9][10] Nerdfighteria is known for its online collaborative nature: forums, spinoff blogs, meet-ups, and charitable events have been spawned by its members.
[13][14][15] Another Nerdfighter club was founded at Auburn University, in which the members have stated their desire to do charity work with The Humane Society and This Star Won't Go Out.
[16] The Nerdfighter subculture's outpouring of support helped convince Penguin Books to release the novel The Fault in Our Stars five months early.
A prominent symbol in Nerdfighter culture is a double-handed gesture with crossed arms, with both hands in a v-symbol, similar to Star Trek's "Vulcan salute".
To decrease "world suck", the Greens founded a charitable nonprofit organization, in which Nerdfighters collaborate to promote social activism.
[35] Nerdfighters are the third largest community of lenders to Kiva.org, a nonprofit organization that helps people lacking access to traditional banking systems by granting loans to them.
[40] The event, initially known as the "Nerdfighter Power Project for Awesome", launched in 2007, and occurred annually in December until it was moved to February in 2021; the 2020 iteration was canceled due to the effects of the COVID-19 pandemic.
Aside from charity drives, Nerdfighteria also offers funding and support for AFC Wimbledon, a fourth-tier football club in England.
[46] Ad revenue from John's videos on the Green brothers' YouTube gaming channel, Hankgames, go to sponsoring and supporting the football club.
[51] In April 2016, John announced he would be making a "docudrama" with "comedic moments" about the story of AFC Wimbledon, set to be distributed by 20th Century Fox.
[52] Another nonprofit foundation associated with the community is This Star Won't Go Out, founded by Wayne and Lori Earl in memory of their daughter, Esther.
[53] Two days after her death, the VlogBrothers made a video titled Rest In Awesome, Esther, remembering her and all of her contributions to the Nerdfighter community, as well as the world.
Other Pizzamas merchandise has included stickers, blankets, rugs, guitar picks, tote bags, LED "neon" signs, and Chizza John (a decorative planter inspired by Chia Pet).
[60] The campaign was successful, and public pressure from the community caused J&J to announce its deal with the Stop TB Partnership a week earlier than originally planned.
The campaign calls for Cepheid, an American molecular diagnostics company owned by Danaher Corporation, to lower the cost of its test cartridges, which are used to detect diseases including tuberculosis.
