Odeo "Voice Message" Button for your Blog

How absolutely cute is this? [Odeo|htt://odeo.com] (the podcast host started by the founders of Blogger) has added a fun little button that allows subscribers to add a voice mail feature to their web pages. I just added one on the right sidebar. If you have a mic, feel free to leave me a message. While this may just be a cute toy, it would seem to have some other useful applications, right?
