I used to like it, now I avoid it at all cost. The problem is that the algorithm is never neutral, even if it's made with good intentions it can be gamed and manipulated, and it traps you in a spiral where what you interact with is what it shows you is what you interact with is what it shows you...
I never really used Twitter or any similar service, so I never had this happen to information shaping my opinions. I did, however, feel that the music I was listening to became shaped by the Spotify algorithm, and that I ended up listening to less rather than more diverse music than when I was sticking to vinyl. That's absurd - you have all the music in the world at your fingertips, and you end up limiting yourself more. That was my experience of course, other people probably have different ones. Anyway, I cancelled my subscription.
If there's a risk for music streaming services narrowing your field of vision, platforms shaping your opinions are downright scary. Algorithms can be tricked into showing you content, which is what russian troll farms excelled at. Tech bros tend to believe the solution is in adding more and more complexity to the point where nobody understands how it works - this is the opposite of how I want the content that helps informing me about the world to be curated.
I'm obviously not diagonally opposed to algorithms. The choose your own algorithm approach might have some merit, and I look forward to seeing more experimentation with this in the fediverse. But I do not trust corporate interests with any of this - nor do I trust a bunch of tech-optimistic rich man's sons.
