We had Gretchen Vogelzang from MommyCast speak at the DC Podcaster Alliance Meetup. She gave a great talk on how to attract an audience. The meeting audio is here (she starts about 30 minutes into the recording). Download the files Meeting audio for Sat., 8-9-08, Part 1 and Meeting audio for Sat., 8-9-08, Part 2. You can download the audio recording here for free. Some really good ideas, be sure to check it out.
