It is a great pity to see that folks who have commented on your blog and are at all critical have had their comments deleted. Even my comment "A number of comments have been deleted, why is that?" was deleted. With a reply from bevacqua "Because they didn't bring anything to the discussion besides "fuck you, you are wrong" AFAIC they definitely added to the discussion by raising opposing points of view and balance which is of interest to me. I firmly believe that comments that are on topic and not slanderous etc. should never be deleted from any blog.
