A bit more on the gender-bias affair (excerpted from the aforementioned deleted post), because I’ve seen a number of commenters who don’t seem to be aware of this:

A few years back an article (with a subsequent statistical analysis) was written about F&SF‘s submissions to determine if indeed there were fewer women being published.  You can go read the article and/or the analysis, but basically, the data indicated that F&SF received far more submissions from men (so naturally we published more stories by men); however, of the female authored submissions we did receive, we published a higher percentage of those, compared to male submissions.
