A big change from Facebook with the introduction of the Subscribe feature. It’s been said that Facebook reaches friends but Twitter reaches the world. But the i ntroduction of this feature moves Facebook closer to Twitter and Google+ where the emphasis is on ‘following’ rather than ‘friending’. Friending is not disappearing but the Subscribe button allows you to have subscribers to your public posts. It will appeal to people who have a strong personal brand eg journalists, pundits, authors, actors, musicians and perhaps politicians. The feature allows people interested in someone else to receive updates without the need for friending. At one level it’s just a link but the Subscribe function moves Facebook from a closed to an more open network. An interesting development.
