puush is a super-quick way to share screenshots and files.
Requires an user account on http://puush.me
Use keyboard shortcuts or drag-drop gestures to quickly capture any portion of your screen or upload any file. These files are near-instantly puush'd, leaving behind a short URL in your clipboard, perfect for sharing. Paste these easily into your Twitter, IRC or IM clients. Share them with the world or make them private, for your eyes only.
