here's my take on reading comments from the dom:
jQuery.fn.comments = function(location) {
var location = location || "inside";
var comments=[];
this.each(function(){
if (location == "inside"){
var children =this.childNodes
for (var i = 0; i < children.length; i++){
var child = children[i];
if (child.nodeType == 8) comments[comments.length] = $.trim(
child.nodeValue);
}
}else if (location=="after") {
for (var next = this.nextSibling;next;next = next.nextSibling)
if (next.nodeType == 8) comments[comments.length ] = $.trim(
next.nodeValue);
}else if (location=="before") {
for (var prev = this.previousSibling;prev;prev =
prev.previousSibling)
if (prev.nodeType == 8) comments[comments.length ] = $.trim(
prev.nodeValue);
}
})
return comments;
};
Tested in Firefox 2.0. & Opera. Along the way I found that in FF comments in
a <noscript> are not broken out in the dom. A minor inconvenience!
and in Safari comments from the original page are not include in the dom. A
major inconvenience!
Oh well!

Could be a cool addition to the metadata plugin. It's more semantic in
my opinion to have the meta data in a script tag if you don't wan it
directly attached to a dom element, but it would be cool nonetheless.
