title: An entire website with node.js and mongodb?
body: <p>I've build several websites using PHP and mySQL as backend, and believe that I'm fairly familiar with both. However during research for my new website I've come across node.js and mongodb (and socket.io, since the site is gonna contain a chat).</p>
  
  <p>I've decided to use node.js and mongodb to run the chat - but don't know if I should just do the entire site with those two things?
  Since I'm gonna run a node server anyway should I just run another (seperate) one hosting the website? Or is that an bad idea? - is it stable?
  I could do the programming in PHP and still be using mongodb - but wouldn't node be way faster?</p>
  
  <p>And another question:
  I've planned to use ajax to handle all the posts to the page - but since I'm allready using socket.io to the chat - should I do all my post request using that?
  For the ajax I've planned to use jQuery (also for all frontend effects).</p>
