We recommend Tweepi for LinkedIn Twitter Follow Back use.  Here is a quick overview.

  • Has a free level of service.
  • Automatically reads in your Twitter account, including who you follow and who follows you
  • A tab enables you specifically to see who is following you that you do not follow.
  • You can click to follow those Twitter users.  If you’re at a Twitter limit, you can click to add those Twitters users to a private list on your account.  When your account is freed up, open your personal list and add the list members.
