title: Difference between ASP.NET MVC 1 and 3
body: <p>I made several websites with MVC 1 and now I'm ready to skip the version 2 to go ahead and play with the version 3 directly.</p>
  
  <p>Without giving to much details, can you provide me with the biggest key concepts that the version 3 brings to the table versus version 1 (version 2 included)?</p>
  
  <p>I will research on those topics afterwards.</p>
  
  <p>For example I heard about "areas" in v2. I'm looking for those big things you programmers think it's worth to know.</p>
  
  <p>Thanks</p>
