The blogosphere tends to uninteresting and repetitive discussions of the “difference between science fiction and fantasy”. Recently, however, we have seen a couple of people put a bit more thought into the issue. One such commentator is our own Karen Burnham, who has developed a rule of thumb for distinguishing between the two. The other is Hal Duncan who, as you might expect, has gone on rather longer on the topic, and mines the darker corners of the dictionary along the way. Both are worth checking out.
