Have ten client appointments you have to cancel tomorrow because you got stuck in trial?  Don’t have the staff to do it for you?  Try Pheeder.    Here’s how it works:

Enter your phone number, plus the numbers of the friends/clients you want to contact.

Pheeder will call you so that you can record your name and a message.

After you hang up Pheeder will call all of your friends. Pheeder will tell them they got a message from you and then it will play your message.

If any of your friends records a reply to your message, Pheeder will call you back so that you can hear their replies.

There is no step 4. This is pretty simple really. So give it a shot!

I haven’t read their privacy policy, and don’t speak to the ethical issues of offloading client numbers and a message to a third-party service, but this is yet another cool Web 2.0–ish application that gives a peek into what’s possible.  Did I mention Pheeder is free?
