DotNetKicks is a Digg-like site focused on .NET development. Thanks for Jon Galloway's useful tip, I figured out how to add a dynamic Kick image to my posts. He has Javascript code, but I just hard-coded the following into the DasBlog itemTemplate.blogTemplate file for the theme in use:

<a href="http://www.dotnetkicks.com/kick/?url=<%PermalinkUrl%>"><img align="absmiddle" src="http://www.dotnetkicks.com/Services/Images/KickItImageGenerator.ashx?url=<%PermalinkUrl%>"></a>&nbsp;

I have not figured out how to dynamically make the link appear only when a specific category such as .NET is selected, but this is good for now.

Of course, this is of no use if I don't post anything worth kicking.
