The BNET article gives a good summary. “Think dialog, not speech.”
This is good news – I enjoyed using early versions of Dojo, and I had hoped they’d keep continuing to improve the product. Looks like they have!
PS: Short, shameful confession: when I first read this article, it sounded so authentic I thought it was actually written by Nielsen. In fact, it was a spoof based on a Nielsen article about frames, but it’s funny how many of the same criticisms apply (frames destroy navigation, etc.).
