Especially if you’re active, or intend or hope to be active, in the greater science fiction/fantasy writing community: sf writer Laura J. Mixon (aka Morgan J. Locke) provides an exhaustive investigation and analysis of the work – if that’s the appropriate word – of a “new, young” writer who turns out to be a well-known internet troll with a long-term record of personal attacks and community destruction.
(No, I’m not giving that person’s name(s) here; I have no desire to give them any more Googlejuice, or to set myself up as a target for somebody to punch full of holes. But the blog post at the link will provide.)
As far as writing advice and philosophy go, two associated points that are more directly in line with the concerns of this blog:
First, this person’s personality and their pattern of bad behavior do not stop them from being a good writer. Even a cursory look at the history of world literature should suffice to demonstrate that the gift of being a good writer and the gift of being a good person come in two separate baskets, and it doesn’t always happen that an individual gets handed both.
Second, it behooves all of us to be careful and charitable about what we say to and about our readers and our colleagues, because the field is close-knit (not to say incestuous), and the same faces will keep turning up around us in different contexts as the years go by. And these days, the internet is forever; somebody will always have saved the emails/kept the screencaps, and the truth, however embarrassing or inconvenient, eventually will out.
