Tyler Cowen shared Audio Guestbook via Sunday blog post.

Audio Guestbook is a service that sends a telephone to an event host so that guests can leave a voicemail instead of writing in a guestbook. In addition to sending the voicemails left at the event via digital file, Audio Guestbook will also send vinyl.

I wonder what genesis question the founders asked themselves. What if I could just leave a voicemail instead of write a message in a guestbook? Hey, wouldn’t it be cool if there was a phone here that I could leave a voicemail instead? Maybe it would be cool if that phone looked like the bat phone or something…

I met someone who thought creativity was an activity meant for artists. I disagree. Anybody can ask the question. The real skill is indulging the question longer than you think you should. That’s where the magic happens - at the margin of should.
