Facebook launches New Subscribe Button allows one to follow an unknown person’s public feed

Facebook launched New subscribe button that would facilitate access to the news published by our contacts, making customized content subscriptions reported by each of them. The Facebook Blog discuss their features, allowing you to configure the access to the news of three categories: All, some or only the really important.
In facebook subscriptions have the page that allows us to create the button on our profile, allowing subscribers begin to grasp who may decide the kind of content you want to read. It is important to remember that subscribers can only see things that we share publicly. They can also choose the amount and type of public who want to receive updates. To let people subscribe, go to the Subscriptions Page and click Allow Subscribers.
Once you allow subscribers, you can decide who can comment and what notifications you get. You’ll also see a Subscribers tab on your profile, where you can see who subscribes to you. So going to make full use of Facebook New subscribe button or not going to enable it for security-privacy concerns?
