There's something seriously wrong with Blogger's comment feature. The problem is not restricted to this blog and has already been reported by many others on the help pages. As you will notice, the recent comments features doesn't work, and in fact new comments don't appear - including my own. There is nothing I can do about it. I do receive your submitted comments by email, but I don't know when they will appear. I'll let you know when the problem has been resolved.
PS: Here is the forum thread where you can report your problem.
Update, July 6, 6:20 pm CET: Comments seem to be working again... At least partly. The comment count still doesn't work.
Update, July 7, 7:00 am CET: All is working again.
