CloudApp is live

Needs to be somewhat polished but it works!

In short, one keyboard shortcut will give you a shortened URL to share whatever you're currently dealing with. For example, if I select a file in the Finder and hit the shortcut, it's uploaded to my account and a link is automatically added to my copy/paste buffer. If it's a web page, just the URL is shortened and placed in the buffer. There are a bunch of plugins ("Raindrops") to decide what to do in each case, with included ones covering the basic Apple apps (iTunes, Finder, Safari) and extra ones for things like Chrome, Aperture and Photoshop.
The whole thing is presented gorgeously.
History, download counts, and web access to uploaded files sweeten the deal.
Why would you prefer longer URLs?
