The tags are part of a service with a wider scope, which offers to businesses tools such as reporting that are key for assessing the effectiveness of a campaign or similar: gathering usage statistics is necessary for offering that kind of service, hence I am not sure if the &quot;but&quot; applies :-) but then again I am not associated in any way with the Tag team, hence all those are JUST my PERSONAL views &amp; opinions </p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9311127" width="1" height="1">http://blogs.msdn.com/b/vbertocci/archive/2009/01/08/let-s-see-if-you-figure-this-out.aspx#9302666Sat, 10 Jan 2009 00:13:48 GMT91d46819-8472-40ad-a661-2c78acb4018c:9302666Vibro.NET<p>Let me spend few mins to write a lunch time post for giving the solution to yesterday's riddle , reported</p> <img src="http://blogs.msdn.com/aggbug.aspx?PostID=9302666" width="1" height="1">http://blogs.msdn.com/b/vbertocci/archive/2009/01/08/let-s-see-if-you-figure-this-out.aspx#9302082Fri, 09 Jan 2009 18:18:07 GMT91d46819-8472-40ad-a661-2c78acb4018c:9302082Andrew Yeomans<p>And work much like <a rel="nofollow" target="_new" href="http://tinyurl.com/">http://tinyurl.com/</a> </p><div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9302082" width="1" height="1">http://blogs.msdn.com/b/vbertocci/archive/2009/01/08/let-s-see-if-you-figure-this-out.aspx#9301310Fri, 09 Jan 2009 07:25:44 GMT91d46819-8472-40ad-a661-2c78acb4018c:9301310Pamela<p>You are evil. &nbsp;EVIL I say....</p> <p>:)</p><div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9301310" width="1" height="1">http://blogs.msdn.com/b/vbertocci/archive/2009/01/08/let-s-see-if-you-figure-this-out.aspx#9301250Fri, 09 Jan 2009 06:24:33 GMT91d46819-8472-40ad-a661-2c78acb4018c:9301250infoblog &raquo; Let&#8217;s see if you figure this out&#8230;<p>PingBack from <a rel="nofollow" target="_new" href="http://blog.a-foton.ru/index.php/2009/01/09/lets-see-if-you-figure-this-out/">http://blog.a-foton.ru/index.php/2009/01/09/lets-see-if-you-figure-this-out/</a></p> <img src="http://blogs.msdn.com/aggbug.aspx?PostID=9301250" width="1" height="1">
