title: Is Windows Workflow widely used?
body: <p>I read a bit about the overall idea of this technology but it reminds me of a few decades ago when we were told "in the future you won't write code, you'll connect boxes in some graphical tool".</p>
  
  <p>Is it a technology which has become central in .NET development (like WCF and WPF have) or has it failed to catch on?</p>
