title: Is Rx framework really "Reactive"?
body: <p>I am going through the Rx framework materials through net, and I have found a plenty.</p>
  
  <p>Now whenever I google around for that, I also found the "Reactive Programming" the wikipedia link.</p>
  
  <p>As reactive programming is about the a := b + c, (a changes whenever either b or c change).
  and Rx is about subscribing to the observable sequence published by the source. </p>
  
  <p>Can someone please explain what exactly the link is between reactive programming and Rx ?</p>
