I picked up most of the podcasts through Itunes, and listen to them in my car. It's so interesting that I almost enjoy traffic !!!!
I'm a Programme Manager, working in IT field in a US company. I'm living in Brazil, and from France in fact.
I understand very well the effectiveness of yours explanations and tips. However I always try to adapt that to other cultural environment, and it's not that easy, in deed.
Anyway, I learned a lot, and keep on listening to these podcasts
