Described as a mishmash of existing services (Twitter, chat, file sharing) that has only attracted attention because its founder was behind Digg, things didn’t look good for Pownce.

Pownce miraculously lives up to the hype. Don’t judge it before you test it.

And it is this: on Pownce, you can send a message, or a file, or a song, or an event, to one person; or three of your friends; or only your family; or everyone.

That’s right, you can engage in private conversations, you can speak to the world, you can have a group of close friends, and a group of associates, and a group of unknown people you just added to your profile, and you can choose when you want to send stuff to any of these groups.

Although seemingly just another IM app, Pownce brings enough cool features to the table to make us want to leave all our IM services behind and switch.
