After some problems with the regular expression I used to read cookies, I decided to do a little rewrite of the code. This cookie problem is fixed now. You'll find the new code below.
Spam protection was something I wanted to add. Too bad I didn't get it working on all my blogs in Internet Explorer (it worked fine in other browsers). I'll leave the code on this page and keep it embedded on my test blog for anyone who would like to test it. If anyone has ideas on how to get this working under Internet Explorer please let me now.
Note that you'll have to remove some lines if you want to use Blogger's spam protection and please read Blogger's help on spam protection first.

How to use this code on your blog? It's simple. Search your template for </BlogItemComments>. After it you should paste the code. Now change the link to the comments. Your don't want it to point to the standard form.
<a href="<$BlogItemPermalinkUrl$>#comments">Comments (<$BlogItemCommentCount$>)</a>
You can also download an example of how to embed it in Douglas Bowman's Minima template.
