As a two-time victim of Adobe dead-ending software, I hold no hope out for NoteTab. Steve Rubel of Micro Persuasion describes it:
Adobe Labs is working on a concept project called NoteTag that allows users to capture notes during meetings and assign tasks within those notes to individuals. NoteTag can turn the notes around and post them to a blog or del.icio.us and tag them.
I bought Adobe PageMill, which the company later lost interest in. (I now use Nano WebEditor.)
I still use Adobe PageMaker, which the company also lost interest in a few years ago. Unfortunately, I am too efficient in using PM to ever think about cross-grading to something else. (I tried Quark Xpress for one book project; it was dreadful.)
I espect Adobe to do the same for NoteTag: develop it, release it, abandon it.
