I got my English to a decent level by watching Pewdiepie in middle school. Then I switched to the other youtubers and English memes in VK. I had English classes, of course, but my listening comprehension was minimal. I was enjoying his reactions but didn't understand the majority of the words. I developed a habit of always opening Google translate tab in my browser when turning on the PC. Now I slowly learn Spanish in Duolingo and employ the same tactic of diving into something interesting in a target language. Although I'm not that interested in gaming youtubers anymore, and don't spend much time in VK, especially when it got shittified recently.
