What does it mean to "follow" someone on here?

Just wondering because I clicked my profile and noticed I had followers I had no idea about. And I follow a number of people but there isn't any real indication that i follow them. I.E notifications when they post or start a thread etc....

Maybe you get notifications when they post something

Think it just replaced the old friends list.
