ATP has a lot of Apple talk, but the hosts fit the bill you describe as I’m pretty sure they’re all left of center. Not that politics come up a lot, but there certainly aren’t any off-color jokes. ATP’s John Siracusa hosts another podcast with Merlin Mann called Reconcilable Differences, and Merlin Mann hosts another I like called Back to Work, and they talk a lot about tech as well. Neither is a strictly tech podcast but I enjoy them all the same.
This is fascinating, thanks so much for sharing!
