Like the Web 1.0 era, the Web 2.0 era has seen some pretty durable successes. Transactions over the medium are here to stay, they aren't "weird" any more. Your portal to technological offerings is not a "PC" any more, it is an increasingly obviously mislabeled "phone." Margins on communication "services" have been commoditized away and seem unlikely to ever return.
I'm looking forward to the next thing, what ever it happens to be. The most fun is always the first third of a wave. The swell, the hint of powerful forces just under the surface waiting to be tapped, the anticipation of successfully getting enough ahead to start the adrenaline fueled ride.
Never a dull moment in a place like this.
