title: jQuery plugins vs widgets
body: <p>Few months ago I started some experiments with jQuery plugin. I found some tutorials on the Interenet and I started to put something together.<br>
  A couple of days ago I had the need to build my own "plugin" and got back to my old project. Trying to find some more informations on the internet, I bumped in these new "things" called widgets. </p>
  
  <p>For what I understand I should forget about plugins and start developing widgets. 
  Are the plugins an old concept or are still valid?
  What is the best approach if you need a custom jquery control with interface?</p>
  
  <p>I am using extensively jQuery UI.</p>
