John Head asked me for some help in getting a new third party service integrated into the the IBM Domino Blog template.  The new service, AddThis, aggregates your bookmarks to a large number of bookmark sharing sites like del.icio.us and Digg.  In addition, it tracks how many people use your button to share your page.  To add this to your own blog, use the following code:

<!-- AddThis Button BEGIN -->
<a title="Bookmark and Share" href="http://www.addthis.com/bookmark.php" target="_blank" onclick="window.open('http://www.addthis.com/bookmark.php?wt=nw&pub=Phigment&url='+encodeURIComponent('<$DXURL$>dx/<$DXDocumentLink$>')+'&title='+encodeURIComponent('<$DXSubject$>'), 'addthis', 'scrollbars=yes, menubar=no, width=620, height=520, resizable=yes, toolbar=no, location=no, status=no, screenX=200, screenY=100, left=200, top=100'); return false;"><img height="16" alt="Bookmark and Share" src="http://s9.addthis.com/addthis16.gif" width="16" border="0" /></a>
<!-- AddThis Button END -->

The Blog specific changes are in bold. The only thing you need to change when putting it on your site is to replace the pub attribute in the link URL with your account name at AddThis.  There are other icons to choose from besides the red and white plus sign I am using, so take a look on their site and choose the one that's the best for you.
