I have the "Digg This" button on my wordpress page (www.badastronomy.com). Here is the code I use:
<p>
<div align="left">
<script type="text/javascript">
digg_url = '<?php echo get_permalink() ?>';
digg_topic = 'Space';
</script>
<script src="http://digg.com/tools/diggthis.js" type="text/javascript"></script>
A couple of my pages have been submitted to Digg, but the link does NOT go to my blog entry. When you click the button, it goes to, for example, http://digg.com/business_finance/bizleading.com (from the Digg button here: http://www.badastronomy.com/bablog/2007/09/18/google-moon/). I cannot figure out how this was done, or if this is on my page or at Digg! Has anyone else had this happen? I am running WP 2.2.1; I plan to upgrade soon, but I don't think that is the root of the problem.
