In-Depth ajaxWrite Review
The definition of a word processor needs updating.
One big document is not always how writers work. That's not how I work, that's not how I think. I like to write lots of different fragments, rearrange them, and then piece them all together later.
I use AJAX sticky notes at http://www.protopage.com/ as my word processor.
It doesn't look like a word processor - but then the decades old definition of a word processor I think needs to be updated.
