Social Networks are getting scary: Part II

I loved using social networks until I got scared of it. I tweeted/shared everything. From what I am reading to which political party I support. One day, it struck to my mind that each tweet/post is a dot and if you connect all the dots then important pattern about me could be revealed. If somebody/organization/government analyzes all my tweets/posts, then he/she/it could easily tell who I am, what I do, what I think, and certainly a stronger algorithm could also accurately predict what sort of the person I am and even predict my future. These possibilities are serious breach in my privacy.
