I understand the desire to educate, but there isthere's something deeply wrong about the proposed design.
The net effect is the user seeing this broadcast in their face in the most obtrusive way we can:
You've done something wrong. Click here to learn why you suck.
You should only send the user obtrusive 'in-your-face' messages about how awesome they are.
Messages about non-awesomeness should always be delivered quietly, via a backchannel, in a way that minimizes their impact. Otherwise, we're slapping them in the face.
