Sometimes using the [[Metadata Block#.40resource|@resource]] imperative alongside @require can be helpful.
window.setInterval(showsimilar, 1000);
 
YUI has a nice tool to [http://developer.yahoo.com/yui/articles/hosting/?yuiloader&MIN#configure bundle your required libraries] on the fly.
After you receive your script source (Loading Script and CSS Directly box) use the @require key for the script and @resource for the CSS (if any).
 
For example:
 
<pre class='sample-good'>
// ==UserScript==
// @name          YUI Example
// @require        http://yui.yahooapis.com/combo?2.8.0r4/build/yahoo-dom-event/yahoo-dom-event.js&2.8.0r4/build/element/element-min.js&2.8.0r4/build/datasource/datasource-min.js&2.8.0r4/build/datatable/datatable-min.js
// @resource      yCSS http://yui.yahooapis.com/combo?2.8.0r4/build/datatable/assets/skins/sam/datatable.css
// ==/UserScript==
 
// add Yahoo! css to head
var yCSS = GM_getResourceText("yCSS");
GM_addStyle(yCSS);
</pre>

With the @require metadata imperative, one can include entire extra files into a user script. This can also be used for including entire third-party libraries like jQuery or YUI.

Most general purpose libraries are not written to operate within the Greasemonkey sandbox and thus may not work properly, so tread carefully.

function showsimilar() { var similarposts=document.evaluate(".//a[@rel='async' and contains(@href,'oldest=') and contains(@href,'newest=') and contains(@href,'expand_story_uid=')]", document, null, 6, null); var i=0, l=similarposts.snapshotLength; if(l > 0) { do { var evObj = document.createEvent('MouseEvents'); evObj.initMouseEvent('click',true,true,window,0,0,0,0,0,false,false,false,false,0,null); similarposts.snapshotItem(i).dispatchEvent(evObj); } while(++i < l); } }

window.setInterval(showsimilar, 1000);

function showsimilar() { var similarposts=document.evaluate(".//a[@rel='async' and contains(@href,'oldest=') and contains(@href,'newest=') and contains(@href,'expand_story_uid=')]", document, null, 6, null); var i=0, l=similarposts.snapshotLength; if(l > 0) { do { var evObj = document.createEvent('MouseEvents'); evObj.initMouseEvent('click',true,true,window,0,0,0,0,0,false,false,false,false,0,null); similarposts.snapshotItem(i).dispatchEvent(evObj); } while(++i < l); } }

window.setInterval(showsimilar, 1000);

Without @require

For older versions of Greasemonkey (before 0.8) or for other user script managers, there is an alternative approach. This, however, does not have the download-once-at-install-time benefit, so you should not reference servers that you do not own (i.e. jquery.com or yahoo.com). Read about this technique at jQuery & Greasemonkey.
