What an odd question. These are podcasts. They're always available.
Well, nothing I do is behind a paywall so--nothing. It costs nothing.
It varies a lot by episode.
That really depends where you are.
Mostly, it's because life happened.
I don't play HeroClix any longer so my desire to make new episodes of HeroClix 201 went "poof." Graphically Speaking requires the cooperation & interest of my teenager. There were fewer and fewer people participating in TUDAC so I just stopped even trying; I do have raw audio for more TUDAC stories but haven't felt a strong urge to edit them. Finally, Derek and I have both had otherwise busy lives so The Ongoing Mission has thus far failed to even begin.
Yeah---um. We don't really have one right now, despite what you may have heard at the end of various episodes. Meta and X have gone to the Dark Side. Since I haven't actually produced a new episode in a long time, I haven't fel the need to make PodCascadia accounts for Bluesky or Discord. Maybe some day.
