I just found this amazing entry on Archive.org which contains some wonderful audio blogs for my old online school.
I was living in Milan at the time and students from all over the word would phone a number and leave a message – magically this message would be converted into an MP3 and appear on our company blog.
It seems quite normal in some ways now, but I can tell you this was pioneering back in 2005.
Here’s the link to the Archive.
Below are some examples of audio messages from students and myself.
