Stickr is a way to leave notes for only you or the world to see on any website. You can feel free to share you ideas or any thought you may have about the page where you want to place the note. The 140 character limit is set for each stickr and each has a follow me button so the person who posted the stickr can be followed. You must sign up for free and you have the option to either install the plug-in for your browser or just place the bookmarklet in your toolbar which you prefer. So if you feel the need to leave notes through out the web this is just the thing for you.
