Same for me. Lately my feed is full of Formula One and Debbie Harris of Blondie fame, neither of which is an actual interest of mine. And basically no content from people I care about.
This is my biggest frustration! For some reason, Facebook stubbornly thinks I'm into cars, into Hollywood drama and some other weirdly specific topics. I cannot for the life of me figure out how to indicate that I'm absolutely not interested in any of those topics.
Deep into the ad topics I managed to find a place where I could search for topics and indicate that I would not like to be targeted for those, and that seemed to have done something. But it replaced one topic with another.
It's crazy how they managed to ruin their own product. They're rapidly bleeding real users and it's totally their own fault. Facebook used to thrive with close social interaction mixed with some suggested content that seemed to be actually relevant. Now it's just anonymous filler content and they don't even show relevant posts anymore.
The only reason I'm still on Facebook is because our local town's official communication is through Facebook (sad, I know) and the neighborhood is active there as well. Otherwise I would have happily deleted my account a long time ago.
I tried something like this with the LinkedIn timeline, where they suggest a popular post from a stranger "Because you are interested in topic X". You can indicate that you are, in fact, not interested in topic X and tailor your timeline that way.
But the next day they will show you something "Because you are interested in Topic Y". Where Y is very closely related to X.
I religiously indicated I didn't want to see X, Y or whatever, because I am just not interested in posts from strangers at all. It took two weeks. Then apparently they ran out of topics for me and started right back at the beginning and showed me something for X.
Oh yeah, this is definitely a great observation. Once in a while FB decides I have a new interest and shoves A TON of suggested content in my face, as if it’s all I ever cared about.
And it’s usually the most random things. Dragon Ball Z. Gangsta rap. NBA. Race cars. Marvel. None of these things interest me yet for WEEKS they only showed me those very specific things.
