Nevertheless, I just had a really good podcast idea involving wine.
It would be weekly; short (really short); and wine sellers would kill for a spot on it (if it developed an audience anyway).
Advice would be appreciated, because I think I really want to do this. And I know bupkiss about podcasting.
UPDATE: Getting some feedback telling me other wine podcasts already exist. For the record, I know this. Including the very fine Winecast. But to the best of my knowledge none of them is doing what I have in mind, which is a very specific thing and not just a wine-themed radio-style show.

I'm in the midst of setting up a podcast myself on both a PC and a Mac. If you let me know your platform, I can email you with what I come up with.
On the content side, I know there is at least one podcast on wine that is available through iTunes. You may want to check it out to see what content they offer and how you want to differentiate.
We are in the process of setting up a KAR annex where we will be podcasting. You could join us...
And when I say "we", I mean "Bill".
Mr. Sponge has been a basement recorder for many years (he played in some shit-hot bands in college) and he recommends MBOX. It's about $400 but it comes with ProTools, Reason and a few other really great recording programs. You can get a compression mic from Guitar Center for around $100.
If you don't want to sping for that much, you can find a USB port for about $150. Then all you need is a mic.
If you are just starting out, we suggest this:
with a half decent mic. We used to have one of these that wasn't half bad...
Then all you have to worry about is bandwidth.
If you have any recording questions, please don't hesitate to ask. We've been debating about having a podcast for quite some time. It would be a musical variety hour.
