MacRadio is listed on Blogger & Podcaster Guide, and has been participating in their online The USA TODAY special which I highly recommend. Basically, if someone does a search for a podcast through the Blogger & Podcaster Guide search tool at the bottom of USA TODAY, they can find you.

You can get involved in it as well right now, including a free month in The USA TODAY through Blogger & Podcaster Guide.

There’s no catch other than after the first month there will be a charge if you want to continue promoting to the USA TODAY’s audience. However, they’ve also arranged a 20% discount for you if you find value in the program and choose to continue on.

To get started, here’s all you need to do:

1. Go to http://www.bloggerandpodcaster.com/usatoday
2. Select “New User” and go through 6 Step registration process
3. In Step 2 be sure to select Option #4 and enter `BP’ in Coupon Code box.

They’ll notify you well in advance of the date you’ll be billed, so you don’t need to be worried about unexpected charges.
