I agree with Greenfield’s theory that low self esteem pushes other away on the internet because of my experiences with Facebook and Twitter. When  people have low self esteem, it often shows online, where they want to continuously post to show people how their life is going. This gets annoying to other users, which leads them to unfriend or unfollow the person who posts too much. This inherently leads to the person being unfriended or unfollowed by many friends to develop an even lower self esteem, and they will be more likely to post even more because of this.
