For those not yet in the loop Pownce is a new tool from a team of four, Leah Culver (code and development- yay for us girls!), Daniel Burka (UI and desktop app development)), Shawn Allen (API and desktop app development) and digg creator Kevin Rose, that will more than likely demolish Twitter once officially released.
The official description:
Pownce is a way to send stuff to your friends. What kind of stuff? You can send just about anything: music, photos, messages, links, events, and more. You can do it all on our web site, or install our lightweight desktop software that lets you get out of the browser.
