title: jQuery: is there a reason not to always use live() for click and other functions?
body: <p>I really like using .live() in jQuery for click() focus() blur() and other interaction events.</p>
  
  <p>I do a lot of prototyping, so I find it gives me great flexibility if I want to dynamically add elements. For that reason, I find myself drawn to the idea of using it by default all the time. Is this a good idea, or is this bad performance?</p>
  
  <p>Does using <code>.live('click',function(){})</code> slow things down in a way that <code>.click(function(){})</code> doesn't?</p>
