title: Developing Windows (Vista/7) Gadgets
body: <p>Apart from seeming a few, I don't know much about how gadgets work. Are they special applications, or regular apps with special styled windows?</p>
  
  <p>I can't think of any app I use which has asked me if I want to install a gadget... I'd have thought any application which is typically left running all the time would be suitable... Skype/MSN for example. Am I misunderstanding the point of gadgets, or are they not popular?</p>
