I like the idea a lot.
Monthly updates seems like about right.
I'd prefer that there be some sort of loose organization (with wandering being okay, within reason).
Maybe one regular host and one guest?
-Intro stuff (Toady and regular)
-Guest introduction
-Guest describes some DF experience or something (basically a hook if this is someone's first time)
-Overview of the past month from Toady
-Scamps update (which I'd really like to see).
-Stuff for next month
-Pre-done viewer questions
-Springboard for long term stuff.
I'm not a terrible speech competitor (could be pretty good if I put effort into it), I've always specialized in Extemporaneous and Impromptu events. I think that a free-form interview with a preplanned guide would work best. The guide would be there to fall back. If the scamps update ends up as a discussion of the communities cruelty to cats (which I can say has been comfortingly down lately), then okay. If the questions get answered quickly, I'm sure that two DFers and Toady can talk for a decent amount of time about the future.
I don't know about you guys, but I read everything that I can about DF. The more, the better.
The idea of a non-Toady broadcast is interesting though. Maybe a four or five person "round-table" on some DF topic?
Urist: Welcome to the user podcast for Bay 12 games's Dwarf Fortress I'm Urist . . . intro stuff . . . Today we'll be discusing fort defense strategies. Personally, I go with lots of traps.
Cog: Traps, especially lines of weapon traps can make mince-meat out of most invasions, but I've always prefered good old dwarven troops. A few champions have the advantage of being mobile, and therefore usable against those very fun, hidden . . . things.
*Laughs*
Morul: In most of my forts, I don't bother with defense much. Call it a feature to be implemented, but isolating my fort with walls and channels keeps me safe from any sort of invader, who needs traders?
Discussion goes on to compare merits of defense systems, eventually getting into the more maniacal and original designs. Pictures (poorly drawn, but clear scribbles) for Strife's Rod from God system are near the podcast's place.
EDIT: I'll be more than happy to help in anyway that I can, even if it's just transcipting the casts.
