Personally, I would recommend the Actual Fluency Podcast by Kris Broholm.
I especially enjoy the Polyglot Conference channel where polyglots (those who can speak many languages) give lectures on language learning.
Did you know that every year, there are events all around the world where language lovers would meet, learn, and network? Here are three such events that are gaining popularity:
1. PolyGlot Gathering (Bratislava in May 2019)
2. LangFest (Montreal in August 2019)
3. Polyglot Conference (Fukuoka in October 2019) is the organizer of the YouTube channel mentioned above.
