The story of Dick Grayson, becoming Robin, then becoming Nightwing played out for us, the audience, in the comics in REAL TIME. It wasn't a flashback. We experienced it. So all of Robin/Nightwings successes and failures we were along for the ride. And people that underestimated Robin or dismissed him perhaps had their opinions changed as we watched him "grow up" right in front of us. His relationships, his conflicts with Batman et al felt real to me because he was the window character with which we experienced Gotham city.

Can't wait for his take. Seems he really understands the character.
