Following someone

So I see on our profile pages a button that says "Follow" and I recently got notification that someone is "following me" which maybe means i'm cool LOL

My question is, what does that do for someone, what do you see when you follow someone, is it really something we all should do if we like someone's posts?

Can I get more clarification on what the "follow" feature is and what it does?
Think of it like you having an online fan club. In some way, shape, or form, you made an impression on someone, and that person has chosen to inform you of that impression by clicking the Follow button. It helps them by notifying them of other content, posted by you, that they maybe interested in. It allows you to know who's interested in you, and your postings,' that may not be in your inner circle.

I have one "Follower," which is cool by me. They've been pretty respectful not to troll me from post to post. Greatly appreciated.:thumbsup:
