The notes are shareable with your community, meaning that if you share a note in Acrobat, it won't be seen in ColdFusion. Making the notes viewable by individuals is a much more complex issue that we will put in as a feature request for the next revision.

Also in this matter, I would like to see more share options (referencing RSS Feeds share options). As well as Twitter, maybe a BuzzIt (Google's Buzz). Is there some "feature request" form for Adobe EnterpriseCafe?
By the way, congratulations! Great product!
