I read your earlier article on How to subscribe to a podcast in iTunes but am not entirely clear how to get those podcast episodes onto my iPhone automatically. How do I subscribe to a podcast on my iPhone?

I hear that you've got a podcast you record weekly, Dave. How can I find and subscribe to it ( ed note: it's called the Boulder Open Podcast [iTunes link] ) in iTunes? I'd like to give it a shot and find out what you sound like too!

While your Macintosh is a fantastic audio editing machine, you may have noticed that Garageband can only see one microphone at a time. All is not lost - Apple includes a tool that can be used to create an "Aggregate Device." An Aggregate Device is what Apple calls a virtual input device - a device that looks like a microphone, but as you'll see is actually more than one microphone combined into one option. How to do it, though?

I've heard from a lot of people - including you, Dave - that interviews are a great way to add high-value content to your blogging efforts, and while I have a pretty good idea how to interview someone, I don't know how to find people to interview. Do you have any suggestions?

I've been listening to a ton of different podcasts in the last few months and while most are lame, there are a couple of really good ones. Is there some way I can vote for the good ones or otherwise help promote them, ideally in Apple's iTunes Store?

Over on your business blog I listened to your recent audio recording with Rob McNealy of Startup Story Radio and was quite impressed with how cleanly you chopped out about 20 minutes of the original audio to present a version that's more tightly focused. How the heck did you do that?

I've been using my Mac to record simple audio snippets, pretending I'm a radio announcer, but I want to trim them down to remove my stumbles, stutters, and breathing. How can I do that?
