I've spent the last two weeks on the road, meeting with customers and prospects. It has been enlightening, to say the least. One primary theme has emerged: the Web 2.0 revolution is over. The web has already won. Its chief weapon? Open source.
It hasn't "won" in the sense that every application is now social. It hasn't won in the sense of market share. But it has clearly won in the sense of mindshare and intentions.
