I'd bet serious money that Voat's userbase is older and more male than Reddit's. April Fool's Day on the Internet is the dumbest shit. It was funny when it was the occasional joke you'd stumble across, but now it's like an entire day for the Internet to intentionally be twice as retarded as it already is.
We already have cat GIFs and frog memes 24/7 on the Internet. There's no need for a day of jokes. It made sense when it was serious shit for academics and nerds.
