I can see the objections to this, but I'm excited - it Taylor had never touched the Nightwing solo he'd still feel like an obvious choice for a Titans book (whereas I don't think he'd do great shakes on Justice League), and it sounds like him writing is one of the things that got Nicola Scott involved, and she's terrific.
But from a pure, selfish Character Favouritism point of view I think this is good for Dick.
1) We know that the writer values him, and is motivated to show him in a positive light - so none of that 'out of touch' /'not edgy enough' /'Batman's lapdog' stuff that you could get in other runs.
2) If the run's a success, and his solo continues to be a success, this feels like the best odds we've ever had for a Nightwing-led 'Event' rather than him dancing around the edges of Bat ones.
