The impressively shrewd and thoughtful entrepreneur John Borthwick has a cogent post on the acquisition of summize by twitter and the evolution of what he calls the "now web"-or what I have been thinking of as the "right now web" or the "just in time web" (ie it's there when you need/want it.)

John writes:
"Somewhere in the past few months the way that I experience the Internet and specifically live information changed -- there is a "now web" emerging out of an ecosystem of loosely coupled products. There has always been an immediate, instant component to the web and web communications -- it goes back to mailing lists, IM, email & blog commenting. But its taking on a whole new form -- the density of the conversations and the speed at which they emerge and evolve is different."

Susan sez: We're thinking alot about the right now web with the products we're developing--and soon pushing out to beta. Twitter, summize and the betaworks products John's team is building are among the products and companies we have been closely watching.
