body: <p>Isn't JavaScript enabled in all webbrowsers by default?</p>
  
  <p>if yes, does this mean that i can use Ajax/JavaScript in my webpages without bearing in mind that maybe some browsers wont be able to use my website?</p>
  
  <p>I don't want to create another version of the page to display non JavaScript content.</p>
  
  <p>what do you think?</p>
  
  <p>EDIT: it doesn't seem that gmail is working with JavaScript disabled. and SO works bad with it disabled:)</p>
