If you are a regular user of Twitter, you will gather more followers and you will also might chance up to follow many people you are interested. I am a regular tweeter and I forgot things like when I joined twitter, who I first followed and who was my first follower. It doesn't bother who we followed and whom followed us first, but I was eager to know what I forgot.

Might You be wish to see whom you first followed, who was your first follower, when exactly did you created your Twitter account etc. I searched on the internet and found all in one website, where I could find my first follower, whom I first followed, my first tweet etc.
