There's still the matter of confusion when [name withheld] is responding to [name withheld], though -- and for that reason alone, I'm afraid I have to disagree with your suggestion. It's also the case that sometimes I'm not entirely sure what someone's trying to say unless and until I look at it within the context of his or her earlier comments in the same discussion. If I can't match someone's comment with the context of previous comments, I sometimes can't tell if they're being sarcastic, accidentally saying "can" instead of "can't", and so on. I judge by the content of a comment rather than by name, and I agree that's a good way to do it, but I don't think that needs to be enforced by withholding information from us.
