I couldn't access the comments on my own website for an indeterminate amount of time (at least a week) and had to dig in the sourcecode to find the culprit (now described in bug 1439112). To make a long story short, it appears I got my dasBlog cookies mangled, so if you have the same issue either contact me or get rid of all cookies from www.tomergabel.com.

(If you're using Firefox and don't know how to access your cookies, here's how. If you use IE just go to d:/Documents and Settings/username/Cookies).
