Facebook / subscription button
If you use Facebook, you have been often faced with this problem, someone you meet once requests to be your “friend” on the service, even though you are not friends.
To help manage this problem, Facebook allows people to subscribe to parts of your news feed without having to become your Facebook friend. The new feature feels very similar to the follow button on Twitter, where you choose to follow someone’s feed.
Facebook said the feature was also designed to help reduce clutter in a user’s news feed. To make it easy maybe you’d like to see more stories from your best friends, and fewer from yourcolleagues.
By subscribing to someone you can decide which updates you see. For example, you can choose to see only photos from a user and not receive updates about a new Facebook game that user is playing.
Stay tuned.
