Canadian podcaster and musician Sean McGaughey has launched an initiative call K7 Days (in Facebook) to increase voice feedback for fellow podcasters.

The K7 reference is an acknowledgement that most podcasters use the free K7.net voice feedback service which provides a Seattle-based phone number and emails digital recordings of voice messages to the user of the service.

Sean’s blurb reads as follows:

A lot of podcasters use the free K7 voicemail service to receive voice comments. A drawback of the service is that like many free internet services, if you don’t use it for 30 days, you lose your K7 number. I also know that podcasters love to receive voice feedback, so I have a simple proposal:

I am declaring the 7th, 17th and 27th of each month as K7 days. On a K7 day take 7 minutes to leave voice feedback for some of your favorite podcasts.

I am all for this. By the way, the voice feedback number for MarkBlevis.com, JustOneMoreBook.com and ElectricSky.net is +1.206.350.6487.
