In the previous article, we discussed why you might want to use the popular “microblogging” site Twitter. In this blog post, we will discuss one of the main features of Twitter, the ability to “follow” other “Tweeters.” Following someone on twitter means that you are subscribing to their account, and you are interested in what they have to say. The tweets of people you are following will appear on your feed when you open your home page. Following a user doesn’t automatically make your tweets visible on their feed. They won’t see what you are tweeting unless they follow you. You will find that the vast majority of people that you follow will automatically follow you back.
