The Asimov story I linked to yesterday is actually one in a series of Killer Robot postings from a combined Gizmodo/io9 sequence. Airlock Alpha (the former Syfy, before a certain channel bought the name) has quite an insightful article about how not to do Cons I can recommend. And Libravox has unleashed the 12th Short Science Fiction Collection of stories, including tales by George O. Smith, Jack London, and Edmond Hamilton.
