Twitter offers one of the most widely used APIs (application platform interface)) in the world, allowing other businesses to create apps that will heighten the experience of using the Twitter platform. Among these apps are games, tracking apps, picture apps, and also apps that will better your chances at engaging a larger pool of people.
There is an app out in the ether right now called Tweepi. It has been around for a little less than a year and is still evolving, but it has found a place as the Twitter janitor and also the Twitter stat machine.
What Tweepi does is it allows you to clean up your Twitter feed, follow the people you will make the biggest impact with online and unfollow the people that don’t follow you. There is also a non-free Premium option that will give you more options for tidying.
