Could use some feedback

[DJ Trashy]

OK, I have a podcast, but it's not your typical podcast. (and I'm not the typical KATG listener either - ha!) It's just pushing bumper music at podcasters. Of course, KATG never use any so I'm not pimpin' myself, just have a few questions in no particular order:

1) I'm currently on Podshow - it's fine for free hosting, but if I wanted to avoid future problems (like a sell-off or maybe not getting paid for ads) who would you recommend? I'm only getting like 300 listeners per episode max, keep that in mind.

2) Domain name registration - does KATG have any sort of registrar affiliation? Any other suggestions?

3) Speaking of domains, how important is a separate site for a podcast in the early stages?

4) Feedback - check out an episode and tell me what you think. Keep in mind, I'm not playing full songs, just mostly samples. Is this a viable, useful service to the podcast community? Should I just switch to playing full songs like most other music podcasts? Or should I just add another feed for that?
