Facebook adds "Subscribe" button for following anyone's public updates

Facebook has launched a new "Subscribe" button for following anyone's (non friends) public updates. This is similar to Google+ follow feature and Twitter.

This is not an auto opt-in feature and Facebook-ers have to "Allow Subscribers" before someone can subscribe you. At present, Facebook CEO's Mark Zuckerberg has amassed a massive 5 million+ subscribers and is still growing.

Some common questions

1. Why do all my friends have a 'Subscribed' button?

You've always been subscribed to your friends. With the Subscribe button, you can choose which of their updates you get.

2. Why don't all profiles have a Subscribe button?

Only people who allow subscribers will have a Subscribe button on their profile. If you don't see the button, you can't subscribe.

3. How do people subscribe to my updates?

After you allow subscribers, a Subscribe button will show up on your profile. Your public updates will appear in people's News Feeds once they click this button.

4. If I allow subscribers, what updates will they see?

Subscribers can see only the things you share publicly. They can also choose how many and what types of these public updates they get.
