As a writer I'd be glad to use something like this. I'm working on a book with the founder of a non-profit in DC, and it involves a lot of sharing articles, trading thoughts, and sending documents. We've been using Honey.is which is nice for small businesses but just not as collaborative as we need it to be.
I appreciate Stross too, he always reminds me of The Captive Mind by Czeslaw Milosz... "the writer's essential task – to look at the world from his own independent viewpoint, to tell the truth as he sees it, and so to keep watch and ward in the interest of society as a whole." I think this quotation applies to the article he was writing, and I found this both chilling and liberating.
