Firstly, let me get a little "Grr, you americans with your unlimited data!" out of the way.
My main Internet is a 3G HSDPA connection, and I get 3GB a month, which is REALLY not much, but thats not the point of this. The annoyance of the "Great Australian Bandwidth Cap" is that my ISP as a file mirror that I can request files to. These don't count towards my quota. This is handy for linux distros (they also have an ubuntu repository) but also for some podcasts. Luckily, I can download anything from TWiT, Revision3 or Geeknights. I assume its because you have the Creative Commons here. Anyway, I noticed that each episode I get mirrored has a good 10 other people who download it, so its cool to think that maybe I inadvertently introduced them to GN.
I thought about this because the topic of how people download the podcast was mentioned recently. Instead of just clicking the link, I have to copy and paste it and the entire post into a form. Unfortunately, I can't write scripts. *laughs*
