I wouldn't take your personal experience on Facebook to be universal. Being a public social network, Twitter's toxicity and distortions are much more visible than Facebook's, and the user experience is far less varied because of common touchpoints like Trending Topics and celebrity posters. Facebook is a far more unique experience per user, so personal experience isn't a great way to understand others experience. A lot of Facebook's problems are related to the network you've formed, on Pages you have to follow, or in private Groups. Facebook also serves far more people and is ubiquitous and worldwide in a way that Twitter just is not. That's why you can't really rely on your own judgment of the product and sort of have to fly on instruments (population level data) to understand it. This is also why it's critical to have researchers have access to that data to understand what is going on.
