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...
[EDIT]
Found this, builds on some of the text.
