This whole podcasting thing

I've just spent an enormous amount of time (roughly 5 hours, spread out over last night and this afternoon) learning everything there is to know about podcasting. I'm still a little confused, but a level of grokdom is emerging.

The things I'm still confused about:

1. I'm still not sure about the "feed" aspect of this. I downloaded iPodderX Lite and was able to subscribe to a couple of podcasts, no problem. I even managed to subscribe to my own, but only by cutting and pasting my feedburner address (http://feeds.feedburner.com/Vintagesounds) into the application. What the heck is the XML link for? If anyone cares to help me on this, please do so.
   
2. When I post a new show, does my "feed" know this? How?
   
3. Am I making a mistake in using Blogger? I like the anonymity of it. I like that it is hooked into Google (I like to think that give my blog a little better chance in coming up higher in the search rankings, but I'm probably deluding myself on theat). What do you think?

The things I'm grocking:

1. Podcasting is gonna be huge. Where we are today with it reminds me very much where we were with The Web around the summer of 1995, maybe even earlier. I'm excited about the internet again.
   
2. When the GP (general public) finds out how to use Podcasting to get TV shows and other visual materials, all heck is going to break loose. This is going to break the final "content barrier", which is the unweildly size of video files. Some morning in the near future, I'll wake up, fire up my Power Book, and off load an entire day's worth of viewing pleasure that has been downloaded over night.

This weekend has been what I like to call a Jetson's Moment. Still no flying cars, but we're getting there.
