@devinb has the correct answer here that I'm going to expound upon a bit.
Information, not the deliverer, is the key component of stack overflow and the primary reason I'm here. I don't give two shakes about whether the person providing the answer is "jon skeet" or "fake jon skeet" as long as the answer holds true.
Quite frankly I find it disturbing that a large number of people do place more emphasis on the person delivering the answer than on the quality of the answer. By quality I mean accuracy and truthfulness. Even worse, it's apalling the number of people that won't bother taking even 5 minutes to verify and instead downvote those who provide a solution different from their "chosen" champion... again, regardless of suitability or accuracy.
An interesting aside: There is a sub story in one of Isaac Asimov's books (Foundation series) in which a group gauged how far a society had declined by how far removed said society was in gathering first hand knowledge.
In other words, as more people placed a higher degree of trust in who said a thing versus directly determining and weighing the facts then that society was believed to be sliding into darkness.
To bring this back, you can tell me all day long that feature X is better than feature Y. However, I won't believe you until I test this for myself. I don't care if you were the author of both features or even if the "group think" is that feature X is better. Why? Simply because people are prone to mistakes and the lure of marketing. I'm a small business owner and a developer of high availability systems. Neither profession allows for much wiggle room in the direction I choose and, therefore, the "answer" must be truly correct regardless of where it came from. Hence I verify first, then trust.
So, based on the above, I don't like the proposed feature and think it not only adds nothing to SO but would further detract from what SO is about.
