In terms of numbers of episodes, it's fairly new: The Digital Edge: Lawyers and Technology. But I've listened to parts of the first two episodes and they're both very interesting. I'm going to listen to them in full:
Hosting The Digital Edge are Sharon Nelson, President of legal-tech company Sensei Enterprises, Inc., and Jim Calloway, director of the Oklahoma Bar Association Management Assistance Program and proprietor of Jim Calloway's Law Practice Tips. Thanks for the link to Celia C. Elwell, a paralegal in Oklahoma City.
