There are millions of feeds out there, continually connecting users to their favorite content. Just about everything online except Facebook and Twitter is available via RSS. […]
What makes RSS truly powerful is that users still have the control. The beauty of the system is it that no one can force you to be tracked and no one can force you to watch ads. There are no security issues I am aware of and no one ever has to know what feeds you subscribe to. This may be the last area of the Internet that you can still say things like this.
