We’d like to ask our readers to participate in our reader survey, in order to get a better idea of who you all are, what you enjoy most about our content, and how you tend to access it, along with general demographic information. It should take about 5-10 minutes to complete. You can access the survey here. To thank our readers for taking the time to fill out our survey, one respondent (chosen at random) will win a free one-year subscription to Lightspeed or Fantasy from Weightless Books. The survey ends December 15, 2011. We look forward to hearing from you!
