I've noticed something similar as well. I like to think of it as algorithmically assisted bader meinhoff syndrome. It used to be that you heard of something and then saw it because your brain was now aware of it. Now your brain is still aware of what you've just read but digital systems are also looking to feed you things. They're not working together but having two things working at once makes it happen slightly more frequently than if your brain alone was just working to bader meinhoff you. But now your brain sees more patterns and believes it's getting "bader meinhoffed" more often. It's purely a speculative hypothesis and I'm happy to be proven wrong but it's the best answer I've been able to arrive at for a sort of glitch in reality that I've experienced recently as well.
