I’ll do this myself then, so we can get more action in this thread. They are not in any particular order, and I won’t put anyone before anyone else, as ranking would take a long time. I’ll also largely omit criticism and “bad sides” because, overall, I believe the good outweighs the bad, which is why I follow them. Here are a few different people, so it’s not just the biggest knowledge bases presented: 
• David Greene, Rob Abasalo, and Joshua Dorkin from Biggerpockets. I’ve listened to hundreds of podcast episodes, read their literature, and followed them on various other platforms. They offer balanced views on topics, have great guests, and overall provide quality content.
• Marko Kaarto. The first Finnish book on real estate investing I read was by him. It was a very easy-to-read work, and after that, I started following him.
• Harri Huru. Finland’s best “Asuntopodi” (Housing Podcast), a fantastic blog/book, and even content on TikTok now. I also really like him as a person. I remember when I first found his podcast, I listened through it in a few months during the summer. One of my investing goals is to be a guest on that podcast. He is also one of the people who sparked my interest in real estate investing. I still remember a boring hour-long break at work, during which a tiny interest in researching real estate investing came to mind. Through this, I decided to watch his content to kill time smartly. That spark then turned into a greater interest, and now I’ve absorbed knowledge on the topic like a sponge. It’s funny because the topic of his book is also the snowball effect 
• Gary Keller. I’ve gained a lot of different insights from his books/content. I’ve been less focused on him lately, but I’ve still internalized a lot from him.
• Heikki Keskiväli. Probably a familiar person to many, but definitely one of my favorites from Finnish investing circles. He seems like an honest person who provides rich discussions in podcasts and similar platforms. He knows how to explain things and share them with listeners/readers of different levels.
• Martin Paasi. He does important work on the Rahapodi (Money Podcast) with Miikka Luukkonen, and has surely planted the seed of investing in many, which will have a greatly positive impact on the finances of investors of different levels in the future. When I started, I certainly got a lot of information from those two. Nowadays, I look for a slightly more “advanced” listening in addition to these, even though I’m still quite a novice, so I’m not trying to be “snobby” or anything. However, he played a big role back then, and I still listen to the episodes. I also follow Paasi’s other content.
• Clint Wetherill and Scott Adams. Their show is a newer acquaintance, but these two’s more conservative view on real estate investing among gurus has led me to follow them. I find them to be very “down to earth” types and they question many of the same things.
• The Inderes team. I’m not classifying any single person here, because it’s together that they create this whole. I started by listening to their podcast, and that has somehow led me to write here.
• Manny Khoshbin. A very interesting story/person. He has a lot of aggressive advertising, but otherwise, I’ve enjoyed watching his analyses/produced content. Nothing specific to say.
• Henry Aflecht. Just fun chatter about crypto. Definitely not serious information, but I’ve followed him on social media precisely because of the lighthearted content.
• Buffet/Munger. No need to explain much otherwise, but these gentlemen have interesting backgrounds/stories. Both also offer easily digestible perspectives on things, even a donkey would understand.
• Peter Lynch. I’ve been reading his thoughts for a long time, and he was also one of the first recommendations for me.
