If your pressed for time, like most of us, it sometimes gets difficult to respond to follow requests from Twitter users. Fortunately there is a free service that will help you with this task and free up some of your time.  SocialOomph is a free service that will automate your follows and it's easy to setup.

Open the SocialOomph page and open an account. Under "Social Accounts" click "Manage my Social Accounts". Add your Twitter account information. After you have created your account, click on "edit" your account information.  Toward the bottom of the page check off "Auto Follow". It's that simple. While you're at it, why not send your new followers an automatic greeting. This you can do on the same page as "Auto Follow".
