I kind of stopped using Facebook for a few months as I was really busy with other things and but I recently starting using it again and I saw that you can become a fan of OneNote!  If you love or like OneNote you should be a fan as well, just go here:

Also it looks like Michael has some more details on his blog: http://blogs.msdn.com/michael_oldenburg/archive/2009/08/27/9887136.aspx

If you are already a fan thank you!  It has been fun reading through people's comments and suggestions, please keep it coming.
