As some people noticed, comments on posts were recently blocked and most were removed. There were thousands of spam comments submitted and the approval queue got too big to handle. I see that spammers do not have anything better to do than submit their URL, but I have much better things to do than deal with that. So here the blog starts clean again. Sorry for any inconvenience this may have caused. Most readers send their comments by email anyways, which is still the best way to get a response.
