Article - SFF World Building

For those of a creative writerly bent, the Gnu brings you an interesting article on creating SF worlds from SFF.net. The emphasis here is on SF rather than Fantasy with the onus on facts, planets, "the future" and other technological wizardry. A word of warning - its written by a published SF author so is a little on the heavy side but if you can get past "SF is that class of Fantastic Literature where this divergence is the result of a rational extrapolation of a change in the writer's reality" then you'll enjoy this little nugget.
