  <p>Some say that iFrame is evil.</p>
  
  <p>But it seems that Facebook uses iFrames for the Facebook applications, and dumping FBML (Facebook markup language).</p>
  
  <p>I have never used iFrames before, but is it a good practice to use them if you want to "install" other web applications on your web application.</p>
  
  <p>Also, how do you send data between iFrame applications and your own web application?</p>
