iUnfollow started in the beginnings of 2011 and quickly grew over the years to become one of the most popular unfollow tools for Twitter (check google for "unfollow twitter"). While the visuals have obviously changed, so has the infrastructure. The code has been maintained and improved over iUnfollow's long lived timeline. I am grateful for such a lovely userbase and I hope for many more years to come with all of you!
