Controversy with Facebook's Algorithm

Following up on this post from a few weeks ago about Buzzfeed collecting data about its users, it's been revealed that Facebook experimented on its users by altering its newsfeed algorithm. The metadata issue is a big one, and it's one about which the average user has very little control except to not use services which are necessary for everyday living. (Another corollary to this: smartphones and the services they offer. I've touched on this one before.) In many cases, the best approach may be to simply limit the amount of information you post online, while recognizing that if a major website isn't charging you for its services, it's you and/or your data that it's selling.
