Love the sticky notes. However, most people seem confused by them. Suggestion -- put a little icon next to the "sticky note" post in question that becomes a link if clicked to an explanation of what it is, and says "sticky note" when the mouse passes over it. Just like you do when a post is restored there's a green recycle icon that says "restored post" when the mouse goes over it.
Too many people think the stinky notes are a bug and ask "why is there an old out of sequence post stuck up there? what's going on?
