I love the Starship Sofa - Tony's unbridled enthusiasm for scifi is infectious, if sometimes incomprehensible. While I wish he'd dump the somewhat supercilious JJ Campanella, or at least trim his science coverage to a concise 10 minutes, I have every bit of respect for what Tony is trying to do. Apparently he's struggling a bit with the costs of supporting the Sofa, so if whether you're a new fan or old, throw a few quid in the tip jar to keep the Starship engines fully fueled.
Speaking of amazing female writers, Pseudopod has a great story from Alice Sheldon who wrote under the pseudopodonym James Tiptree. The Screwfly Solution reminded me of the old school scifi that I loved as young reader, flipping the pages of Omni Magazine for the fiction column every month. It's worth a listen. I'm going to track down more by Sheldon/Tiptree myself. Anyone familiar with her can recommend a good book to start?
