What makes you think you are someone I would have dialogue with? The point is.... I don't care who you call yourself nor do I care if you use 'real' information when registering - I care only to be able to say this is the same person who asked a question. I respect your right to privacy and am certain I could care less as to your real identity. If you are concerned about being tracked.... well that pretty much can happen whether you use cookies or registration.
