Twitter announced on its blog Thursday that it has built for itself the ability to change what messages appear in your Twitter feed depending on what country you're in. The result is a selectively censored Twitter experience, based on the laws of the user's country. It comes nearly one year ago to the day since Twitter announced, "Our position on freedom of expression carries with it a mandate to protect our users' right to speak freely and preserve their ability to contest having their private information revealed." Twitter frames the move as an effort to comply with local laws, retain the ability to stay up in a given country and be as open and transparent as possible about the process.
