The catchall category for everything. If you're not sure where it goes, it probably goes here. Literally anything not covered by a real topic.
Official forum threads for episodes of <a href="http://www.frontrowcrew.com">GeekNights</a> and show-related discussion.
Games played on computers, consoles, or brain implants.
Actual political discussion and discourse. If you want to argue in bad faith or be a devil's advocate, go over to Flamewars instead.
Tabletop orthogames, german board games, card games, etc...
Music of all kinds, all genres. Death Metal and Bebop next to Filk and Rachmaninoff.
Movies of all kinds that aren't best categorized as "anime". Classic cinema, garbage B movies, etc...
Phones, PCs, arduinos and ham radios: all the practical or real-world applications of the fruits of science.
Travel to hotels or convention centers where like-minded individuals enjoy a shared experience related to their hobbies or work.
Animation from or generally associated with Japan. No one is interested in arguing with you about what "counts" as anime or not. If you feel like it's anime, talk about it here.
Sportsball! Athletic orthogames like football, hockey, baseball, basketball, F1, etc...
Yo dawg. If you want to talk <em>about</em> the forum itself. Suggestions, complaints, or just ridiculous pedantry.
Comics, graphic novels, manga: anything that involves sequential illustrated storytelling.
Art you have created wish to discuss from an artistic perspective. Illustrations, crafts, models: whatever!
Role Playing Games
Role playing games like Burning Wheel or Dungeons & Dragons.
Actual science discussions, like astronomy, biology, physics, and space travel. If you don't think it goes here, it probably goes in Technology instead.
Wanna start a fight? Argue in bad faith? Be an insufferable pedant? Let's roll.
