I tried to search for them but it difficult as there quiet a lot of them that have alt-right videos. Also I’m not multilingual and only know English which few instance are a different language.
Videos I like watching: -
Linux
FOSS review/showcase
Gaming (such as Fallout NV, Minecraft, Resident Evil etc.)
I know YouTube is somewhat decent video site but I want to try learn other video services that isn’t just YouTube.
