Do you remember your first? First Twitter follower, I mean. Whether you have tens of thousands of followers now or just a few dozen, you started out with the same number as everyone else: zero. And someone had to be number one; the very first person who thought you were worth paying attention to. The first person in the world to click that “Follow” button on your timeline. That person is a hero, really. If you don’t remember who that person was, though, a tool called First Follower can help remind you. It works like this: open up the First Follower page in your browser and type your Twitter username into the box provided. Then press the “Enter” key. That’s it. You’ll then be shown who your first follower was, and will be given the option to share that info via Twitter. You don’t have to type your own username into that box, by the way.
