After I switched to Disqus comments, I noticed that my recent comments widget no longer worked. So I wrote a new widget that adds some JavaScript to the web page which includes the recent comments (and a few other options, if desired) when using Disqus.

The widget is is available on the blogengine.net gallery website.

Known issues
-The character limit when using the combination look doesn’t seem to be working. I need to look into this more, but right now it seems Disqus is ignoring the character count.
