four years ago, maybe more, i remember reading an article about these young guys who had developed some kind of free downloadable software that ended up being like a sort of public sticky-note concept for web browsing. it meant that if you had the system and you visited any site on the web, you could leave a note there -- saying anything you wanted -- and anyone else who came along with the same software could read the notes and/or leave one of their own. i can't recall the name of the company, but i wonder what ever happened with that idea and if people are still using it.
