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.
I wrote a whitepaper evangelizing RSS for the publishing company I worked on in 2005. I proclaimed RSS would be as big as the Web or newsletters. That didn’t happen. On the other hand, Facebook and Twitter are very RSS-like. And I’m still using RSS as my primary channel for accessing many websites.
