Corkboard.me is a simple and handy webapp that creates a virtual corkboard of sticky notes. Changes are saved to your personal, auto-generated URL, letting you share your corkboard with anyone.
As you can see in the above video, the Corkboard.me webapp is very simple. You click an empty space on your corkboard to create a new sticky note and begin to type. You can move it around, resize, and delete. But what makes Corkboard.me a bit cooler than your average sticky notes widget is that you can send your corkboard's URL to anyone and they can not only view your sticky notes but add to them as well. In the future it would be great to see some basic text styles (like font size, font weight, and the ability to make lists) as well as colored notes for better organization (or as a means to differentiate between different creators). Sharing options, such as a view-only mode (for non-creators), would also be helpful. That said, Corkboard.me is particularly nice thanks to its simplicity. While I'd find those features welcome, their absence doesn't hurt the webapp's usefulness.
Corkboard.me is free to use and no signup is required. Just visit the site to give it a try.
