Via Daring Fireball, I stumble across a page of podcasts from the SXSW Interactive conference from last March, and notice that one of them is from a session about maps called “How to Make the Most of Maps.” The description: “Map hackers discuss how to get started on hacking, the differences between mapping platforms, why maps are cool and the future of mapping.” Page down about two-thirds of the way or go directly to the audio file here (MP3 file, 26 MB). The session lasts about 57 minutes; the audio isn’t the greatest.
