LineBreak has released version 1.0 of CloudApp, the best application around for quickly sharing screenshots, files, and links. I’ve been a beta tester of CloudApp for almost a year and it is, hands down, the most useful new app around.

The best part about Cloud is how unobtrusive it is — the app lives in a menu icon and most of its uploading is done automatically. For example, anytime I take a screenshot, Cloud instantly uploads it to their servers and then puts a shortened link to it on my clipboard. When working with teammates, this makes it incredibly easy to share designs or quick thoughts. I simply take a screenshot, go to an IM window, and hit paste.

The new version features “raindrops” — a way for developers to create their own custom hooks into native apps like Photoshop, iPhoto, and WebKit. They’ve also released a web app to manage and organize your uploads.

If you find yourself sharing things throughout the day, give Cloud a try.
