SharedCopy is a website annotation service that comes ready integrated with your Basecamp and Twitter. SharedCopy has a callback mechanism for anyone to plugout to, making it a seamless and simple collaboration service, requiring no dowloads or installations whatsoever. For starters, you can begin using SharedCopy without registration. To make the copy public, you will just hit copy+public, or if that makes you feel uneasy, you can simply make the copy private by hitting, surprise! Copy+private. However, if you want to start locking the documents so that no one many comment on them, it will then become necessary that you sign up for the service. This service functions with your internet or intranet, anyone can see the pages without signing up or using javascript.
