Voice comments for blogs

This is not a SSH post but i thought i shud mention this. So we lost snapvine, but don't worry there are other sites that are kinda like snapvine so that's a good thing. I am looking for some good free voice comment sites where u can i guess embedd a code into the blog so that others can hear. Here are some sites I have found that you can do that:

 Voice2Page
Yodio
Speak a message
SpeakPipe

Have fun!
