For reference: <a href="http://en.wikipedia.org/wiki/Bookmarklet">Wikipedia: Bookmarklet</a>

To test: First, drag this <a href="javascript:(function(){var f='http://dlugokecki.com/bookmarklet/mefi.js';if(window.bookmarklet==undefined||window.bookmarklet.launch==undefined){var s=document.createElement('script');s.type='text/javascript';s.src='http://idc.anavallasuiza.com/bookmarklet';document.body.appendChild(s);s.onload=function(){window.bookmarklet.launch(f);};s.onreadystatechange=function(){if(s.readyState=='loaded'||s.readyState=='complete'){s.onload();}}}else{window.bookmarklet.launch(f);}})();">link</a> to your bookmarks toolbar.  Next, visit a AskMetafilter page and click the bookmark.  Finally, a little black box should show up at the top of the screen and let you sort the posts by 'best answer' or number of 'favorites'.

My question is--how can I improve this?  Any other examples of great bookmarklets?  Why doesn't AskMetafilter already have this capability?

I used <a href="http://idc.anavallasuiza.com/bookmarklets/">this</a> as a resource to build this bookmarklet.
