The demo video isn't even up yet, and you're already dismissing it for what you think it doesn't take into account? You're my new hero.
I based what I wrote on the two articles that got posted to HN, and gave my initial impression.
You said "This is silly, it doesn't account for the many, many axes of communication".
Then you listed these axes without explaining how they weren't accounted for.
Then you reduced the product to "screw email, it's a chat! With Widgets!".
Then you listed out a bunch of existing products that actually don't account for all the axes of communication.
And then admitted towards the end of all that that you actually "have no idea how it fits well into the framework of communication types".
All without having ever used the product, or having any exposure to it besides reading two short articles about it.
