Most writers have run across these pitfalls of writing science fiction and fantasy, but it's good to get a reminder now and then. Vonda MacIntyre's descriptions of these (currently) seven pitfalls are short and to the point. They include neologisms (Garfff brought a carrytab of steaming hot javening with boosem and sweetum on the side), Extreme Capital Abuse, sort of using an almost approximate spoken thing rather than a sensible word, etc.
