We've 'enjoyed' curated content on twitter (by an algorithm) for years now. We are finally able to only see relevant content. Everything else is filtered out 'automagically'! So they would have you think. In reality your timeline is a mix between being chronological and being 'just whatever Twitter thinks will interests you. Hell, we are even able to see favorites from people we don't follow! Isn't that great? The reality is that it is usually something you don't really care about.
I decide what people to follow because I want to read their tweets. I don't care about anything else. If I did I would follow those people too.
I always loved twitter because it was (and still is for now, at least for me and everyone else that uses a 3rd party twitter client) a place where I chose who to follow and what to follow. A place where no one would inject my timeline with their posts or ads, a place that you could shape to your own desire as if it was an RSS feed for short messages or as a group messaging app. Everything was possible. Twitter is is migrating far away from that concept.
