You can comment on blog post, you will see number of comments received in particular post, but you don't see any comment. Don’t be angry by predicting they have deleted my comment, in fact your comments are not deleted by blogger users. Your comments are not seen because of problem raised in blogger comment system. Don’t know why comments are disappearing, reason is still unknown.
