I'd personally love to hear Peter-san start speaking Japanese more again on the podcasts.
I am currently struggling with my speaking ability (it's coming along great but I have such a ways to go); it's really encouraging to hear a fellow Japanese learner (allbeit a much smarter one) be able to have converstations and smoothly create long, complex sentences.
It reminds me that it's possible to nail Japanese. It keeps me going.
Thanks!
