Bruce Sterling is a favourite of mine. Not that I have read that many of his books, but his blogging is enormously inspiring and particularly a design speech he once made at a German university - the Max Weber Institute, I think. Sadly, I've lost the link but it's all about SPIME!
Now, he is closing his Viridian movement, and leaves us with this note. Just waiting for that pivotal moment now...
Found this, builds on some of the text.
