No, MySpace and Facebook didn't what I was asking for because they didn't have any feed then.
With MySpace and Facebook in its early days, I could just stalk profiles and both didn't serve me any content based on my interest. On MySpace I could browse through some music genres but this is not my understanding of an interest-driven site.
However, Twitter is a different beast. They got better over time because Twitter evolved from a friends network to kind of a interest-driven network. At the beginning people were following friends and then you had the same dissatisfying outcome like with FB (nobody wants to unfollow a crap-posting friend and muting wasn't available then). But nowadays you rather follow people on Twitter based on interest or because you share the same industry, etc.
And only if you use a third party client.
Likewise with Facebook when they first introduced the newsfeed. It was literally just a feed of recent activity as far as I remember.
