To better understand how RSS is changing the way companies and individuals deliver and consume content on the macro scale, let us first remember how content is traditionally delivered and consumed. People subscribe to newsletters or e-mail update services for email content directly in their inboxes. It is (or rather, was) convenient, easy and simple. But, in order to get content delivered to their inboxes, they must first reveal their e-mail addresses, which are basically ID numbers that allow anyone who knows what he wants to send to these identification numbers. In a perfect world, people only receive the requested content and only people who wanted to know about – people who can provide them with relevant information specific to your interests and current situation. But this is not a perfect world. Since the "ID number" allows anyone in contact with anyone, people have very little control over who actually gets in touch with them and the information you send.
In a way, is a "perfect democracy" that just does not work. Because in fact we do not want to hear from everyone who thinks they have something to say. In fact, we just want to know about a very limited circle of people and receive very limited types of content categories. But for the sake of argument, let's assume that we are actually getting information only from people who want to hear. Unfortunately, these people still have the power to send any information you like, not only the information that we receive from them.
