title: HTML5 UI Frameworks
body: <p>I found lots of HTML5 UI frameworks over there, such as:</p>
  
  <ul>
  <li><a href="http://www.kendoui.com/" rel="noreferrer">Kendo</a></li>
  <li><a href="http://wijmo.com/" rel="noreferrer">Wijmo</a></li>
  <li><a href="http://www.jqwidgets.com/" rel="noreferrer">jqWidgets</a></li>
  <li><a href="http://zebra.gravitysoft.org/" rel="noreferrer">Zebra</a></li>
  <li><a href="http://www.sencha.com/products/touch/" rel="noreferrer">Sencha</a></li>
  <li><a href="http://sproutcore.com/" rel="noreferrer">SproutCore</a></li>
  <li><a href="http://yuilibrary.com/" rel="noreferrer">YUI</a></li>
  <li><a href="http://xuijs.com/" rel="noreferrer">XUI</a></li>
  <li><a href="http://www.shieldui.com" rel="noreferrer">Shield UI</a></li>
  </ul>
  
  <p>I'm kinda overwhelmed with again so much resources out there.
  Looked some of them, but almost all seemed like too slow and heavyweight.</p>
  
  <p>I'm getting a bit confused about which one will I learn.
  Each of their websites talk about their product as if they were the best on the market. (obvious marketing strategies).</p>
  
  <p>As a beginner on web apps development and client-side JS UI frameworks; you guys, based on your experience which one do you recommend for rapid desktop web apps development considering speed, widget collections, complexity, look n' feel, support, etc?</p>
  
  <p>Which one do you recommend me to start learning?</p>
  
  <p>I know there could be lots of answers and each one could prefer different ones, but this could help to guide me a little and have some critics of some of the most popular frameworks.</p>
