I just deleted my account and switched to an old account and the quality of my recommendations improved by an order of magnitude.

It's probably because I last used that one 10+ years ago when it seems things were a little more lighthearted (at least in my digital world). Going back to that recommendations page in current year was a truly magical experience.

Of course it didn't last though, within a few weeks algorithm was onto me, and went back to showing me the same stuff as on my old account.
