I voted for FB but yeah I really have no idea. I don't get social media at all. I don't get Twitter or TikTok. I don't get how anyone makes a nickel in advertising. I also don't get crypto. They're worth billions based on network effects for reasons I can't comprehend. I understand the internal logic of how they function and monetize but I can't understand how they get so much engagement.
