Does anyone know why, when viewing a particular profile in Twitter, I am presented with specific other profiles of people I might like to follow? Is there some connection between these people and the profile I'm currently viewing? What's going on under the hood, so to speak? When I view the profile of a certain friend, I continually get the same person suggested to me. Yet if I view THAT person's profile, my friend (who I do not follow) isn't suggested to me. Strange, or to be expected? Any info or background knowledge of what's driving these suggestionservices would be really useful. Many thanks.
