@mars1024 well, the issue with that theory is that we have Hashtags, which is the way Twitter got so popular back in 2008-2010.
So, if people would just use hashtags correctly, follow tags, and follow people they enjoy, it's not hard to find content.
Though, there are some niche topics that are rare here. For this, I'd say it's good that Threads and Flipboard are beginning to federate, but there's nuance, like Threads' moderation practices that make people want to block them.😬
