W. Curtis Preston the author of the Mr. Backup Blog recently voiced his frustration with certain bloggers censoring visitor comments. He was annoyed that some folks from EMC configured their blogs for comment moderation (all comments must be approved before they appear on the site) and used the power to delete certain responses. He contrasted this to NetApp whose blogs are not moderated. (As a point of clarification, AboutRestore.com’s comments are not moderated; reader comments are posted immediately.) Whether you believe in comment moderation or not, at least these blogs all provide a mechanism for the visitor to respond.
