Be Aware Twitter Tracks Users

Initially it was confusing to read and write posts on twitter. Many left as they couldn't know whom to follow. Twitter with its suggested user list knew who followed whom. Then publishers placed Twitter buttons on websites to share pages.

Though you don't tweet or don’t have an account—the buttons tracks your data 

(deleted after ten days and not taken from European visitors, due to local laws) on 

website visit, if the publisher or you hasn't opted out. This is how Twitter gets users.
