It's a small change, but Facebook has decided to ditch the word "Subscribe" in favor of "Follow" for all profile pages. This marks a change that brings it in line with the term that Twitter uses to describe the action of electing to receive a profile's public updates.
Subscribe is a bit unclear as to what it does, though once you know what it does, it becomes perfectly clear and acceptable. Clearly, though, not enough people knew what it meant, and this has prompted Facebook to make this change. The function of the button is remaining exactly the same as before.
Starting today we are updating the term "Subscribe" to become "Follow" across the site as we found it is a term that resonates better with people on the service. Nothing is changing about how the feature works.
Did you know what the Subscribe button was used for? Is it a feature that you even knew existed on Facebook? Let us know!
