Chrome Extension Script to convert all title links to open in new tabs. Requires jquery.

linker.js

// JQuery included here...

// A variable to hold the "timeout-id" for our DOM check
var update;

// Page is ready
$(document).ready(function() {

	// The DOM (page) was updated
	$("body").bind("DOMSubtreeModified", function() {

		// Attempt to clear the currently scheduled check
		try { clearTimeout(update); } catch(err) {}
    	
		// Schedule a new check for 100ms time from now
		update = setTimeout(function() {
			fix();
		}, 100);
	});
});

// Any DOM optimizations we want to do go here
function fix() {

	// Make sure all <a> for post titles are set to
	// open in a new tab (target="_blank")
	$('a.title').attr('target', '_blank');

	// I decided I wanted the comment link in a new tab too...
	$('a.comments').attr('target', '_blank');
}
