filter bubbles

I learned that websites and social sites are limiting what we view and what others view. A filter bubble is basically controlling what you view because they're trying to guess who you are and personalize it to what you do. It kind of upsets me because it limits me on the information that I see and read and I like reading and being informed on things. I also believe that its really not necessary to personalize what people read. I'm just going to start using duckduckgo.com because Preston said it doesn't just give you a small percentage of information but all the info.
