Facebook is now testing a new feature that allows users to choose whether or not to subscribe to Friend’s updates on the Friend Request accept option.

In addition to this option, Facebook is also offering the option to receive updates from certain friends on your mobile phone via SMS text messages, similar to Twitter. Actually, both of these upgrades will make Facebook much more like Twitter.

Historically, Facebook relationships have been mutual, although decreasingly so with all of the privacy settings that have been implemented in the past two years. The recent option to “Hide” certain Friends from your Feed was the last major change of this caliber, although it still entailed adding a Friend mutually and then hiding their posts by clicking them from the Stream.
