Whoa. Bracing, intelligent essay in Strange Horizons about reviewing diversity in the SF genre. She's mostly talking about/to professional reviewers, but it couldn't hurt to listen in.
As the diversity of the pool of genre tales being told widens and deepens, more of us want help accessing it. Where do we find the good stuff? How do we know it's any good? This essay intends to address ways in which reviews, and thus reviewers and reviews editors, can help, rather than hinder, based on my experiences on many sides of this question. It's born of controversy, and will probably live and die breathing, drinking, and eating it.
