“Share your opinion with a few hundred friends.”

Blogger Matt Galloway has just invented the new way to spread word of mouth: the Buzz-o-phone.
Just in the last two weeks the Buzz-o-phone has gone from a concept in one blogger’s mind to being described as “the drive-by shooting of the marketing world.”
The idea is quite uncomplicated- anybody can call a toll-free number and talk for up to two minutes about whatever they want. Maybe it’s a product they love, a brand they hate or maybe even what they ate for dinner.
Then whatever the caller records is audible to the whole world as a podcast.
Inventor Matt Galloway believes this experiment will show a little more about how people communicate and how word of mouth is used. He says he’s also wondering if Buzz-o-phone will prompt more people to voice their opinions because making a phone call is so simple.
Since it’s unveiling, the Buzz-o-phone podcast is now available in the i-tunes store and has been featured on Rocketboom. There is even quite an amount of buzz about the buzz spreading device, with articles all over advertising critics’ websites and blogs.
Now there are over 1,000 people calling each day, of course many just to make rude and obscene statements. Galloway also mentions on his blog that he would prefer less shameless self-plugging, suggesting that businesses and the like mention on their websites that they would like to be referred to on the Buzz-o-phone instead of directly calling in themselves.
So what’s to become of the Buzz-o-phone? Will it create overwhelming buzz for products, services, companies? And if so, will this be positive buzz? What are the legal implications as certain people/products are dissed in a one-way phone conversation that can be heard worldwide?
