The Datlow anthologies sell well, so that's a good thing, but being in one isn't going to guarantee broad name recognition or any novel sales, in my view. I've read plenty of anthologies and I can't remember many of the authors in them even when I liked all the stories. He's had two Nebula nominations and one Hugo nomination. All for short stories. Even though these are good things to have in the SF/F community, I don't think having any of these things for short stories is going to translate into success in selling novels. I just don't see the correlation there. I don't think a short story career necessarily translates into name recognition and novel sales. I'm not sure most novelists can afford to quit their day jobs, and people selling in the short fiction markets probably have less name recognition than that.
