If someone is following you, it's so they can keep up with what you are posting, because they like what you have to say. They find your questions interesting, or your answers/comments helpful and insightful.
If they're funny, smart, have similar views to mine, friendly, or just give overall great answers. Also when they answer questions that are actually interesting, so when you go to Connections you'll see some good questions to answer!
As explained above, following someone can mean many things. I follow people for two reasons: the first is to see more answers from someone who has posted answers with which I agree, and that I respect.
The second reason is to keep in touch with someone who has asked a very difficult or painful question, and who has spoken back and forth with me through the comments enough for me to know that my answers to her have honestly helped her.
I love helping our young ladies who are trying so hard to find their way through the pitfalls of young love and dating. I want nothing more than to help young girls understand their own personal power, and to teach them how to use it to become strong, independent young women.
