I love WordPress 2.0 for many of the new features. I don't love it for the couple of bugs I'm finding. I did have Spam Karma 2 running when upgrading from WP1.5 to WP2.0, have installed SK2.1b4 and SP2-WK2 compatibility plugin.
Whlie my installation of WP2.0 does count comments okay in the blog post footer, but on the permalink page, it says "No Responses to (permalink title here)", and then proceeds to show the responses right below. It's not showing the count on the permalink page, e.g. http://www.djchuang.com/2006/01/d1235
