There's still a selection bias towards technically literate, privacy-conscious, left-of-center (or at least liberal) people. Lemmyverse represents such an unthinkably tiny fraction of Earth's populace it's not even an echo-chamber, it's more like an echo-pocket. However, this allows me to feel comfortable here, which is a huge plus. You just have to keep in mind that every opinion that's popular here is not representative of anything but the Lemmyverse.
