Okay, I've just finished listening to all 58 Jongcasts. Absolutely fantastic work - I'm sorry to see it have a bit of podfade (I think one podcast in 8 months probably qualifies) but I realize life and time are at a premium for all of us so this is understandable. Anyway, here are some observations and all are IMHO:

Jenn's personality is kick-ass.

Garth(e) seems to have 4 years of perennial semi-hoarseness in his voice. Is the smog that bad in Tokyo or maybe the 2nd hand smoke in the parlors?

The strategy segments are the absolute
best part of the casts - tons of great info there.

The side stories about travel or where little snippets of Japanese life and Japanese words/culture are revealed are the second best parts of the casts.

The league status is interesting but maybe could be a little shorter since most listeners, presumably, don't know most of those people and since podcasts are preserved for future listeners, most of those events will have come and gone long before we get a chance to listen.

The Garth(e)-bad-beat stories and knocking "lesser" players for playing "bad" (but winning) are the worst part of the casts.

Having one of the Japanese Pros on for an interview (assuming they can speak some English) would be absolute killer.
Overall the Jongcasts are highly recommended - I'll be listening to them a 2nd time now that I have more knowledge under my belt. I hope to see a return of our dynamic-duo in the future!
