HTML Comments are diamonds

So everyone thinks that html comments are lame... well... they are NOT! They can be extremely useful! In fact...

 { return this.nodeType == 8;})
 .after(function(){return this.data})

- Ta-da
- What?
- What did you do that was so "ta-da"?
- Well, using jQuery i just converted all the comments content into actual HTML, so if someone had <!-- <h1>Haters gonna hate</h1> --> it will transform into actual HTML!
- And why would i want to do that?
- You know that comments don't get read by the Google Search bot, right?
- Yeah....
- Well, ajax is cool and all that... but is always faster if the content is already on the current page
- Yeah...
- Mmmm... do i need to make you a drawing or something dude?
- F*ck you.

I know some of you are lame as sh*t and don't love the all-mighty jQuery javascript library so here it is the same code in 100% pure cross-browser javascript (IE7+, Chrome, Firefox):

function find_comments(selection)
 selection = selection || document
 function loop(arr)
  for(var i = 0; i<arr.length;i++)
   if(arr[i].nodeType == 8)
 return comments_found;

var comments = find_comments(document)

for(var i=0;i<comments.length;i++){
 var one_comment = comments[i]
 var div = document.createElement("div");
 div.innerHTML = one_comment.data
 for(var j=0;j<div.childNodes.length;j++){
