One of the things you've done that I really like is the focus on people instead of posts - this shifts the system away from favoring noisy or loud individuals which is the correct sort of shift in my opinion.
It's difficult to know what's better - some people may prefer to see posts, since they may want to find viral memes/videos/takes rather than to have to follow someone's output over time. It seems like a tradeoff to me - similar to short-term vs long-term. So it would be interesting for someone who loves news feeds to rethink them at some point.
