Facebook followers are just the old feature of subscribing with a new name.
Follower just seem to be much more close to the feature core meaning. Everytime we talk about subscriptions, we thing about something related with a recurrent pay.
And one thing is clear more than ever – Facebook didn’t want to start a new dispute about promoted posts as well as other attempts to monetize their social environment. This service is free and always will be like that (they don’t forget to remind this when you join). And showing off the term Subscriber on each Facebook profile might change the claim power.
Also, it seems that the term follower was tested before launching, on some users, and they resonate better with the new terminology, as an Facebook official declared for Mashable.com .
The change started in New Zealand, as many of the new changes and features that FB launches. It is now propagated all over the world so Facebook subscribers will become history very soon.
You can buy facebook followers (or subscribers, if you wish : ) quick and safe.
