I'm checking out Odeo again after not having used the site for months. From their FAQ page, "Odeo is a creative way to record and share audio—and it’s free. You can record audio and then share it with your Odeo contacts, by email, or by placing it in a Channel for all the world to hear. Audio from Odeo can be downloaded to desktops, iPods, and mp3 players."

I've subscribed to a few interesting channels and am going to fire up iTunes to download them for me... although my audio inbox is a bit big after not listening to my subscriptions for so long. One feature I'll try out for a bit is Odeo's voice message system. Click the "Send me an Odeo" button on my site if you have a microphone on your system. It's like voice mail for the Internet.
