I found another online SF/F magazine which would be a good source for short stories and articles. Lightspeed is a science fiction and fantasy magazine published on the internet which can be read for free online. To keep things interesting, the monthly magazine is released incrementally on the web site, with new articles made available every Tuesday morning. So, the first week in December, roughly 1/4 of the magazine was online, with additional content to be available in the 2nd and subsequent weeks of the month.
In addition to online access, the magazine is available in eBook editions which can be purchased directly from the Lightspeed bookstore or from Amazon and Barnes and Noble. The eBook editions include bonus articles not available online.
