*It was a wonderful thing that this very useful term always had an implicit expiration date. Other semantic gestures associated with Web 2.0, such as the use of the terminator "R," are already defunct.
*It seems that "Web 2.0" will always be associated with the five-year period 2007-2012, which seems just and proper. A lot went on at that time which was different in character from earlier periods, yet things are different now. We're entering an unnamed period dominated by mobile apps and vertically integrated social networks, which will itself be quaint by 2017 or so.

"Today I'm putting a stake in the ground: "Web 2.0" will die on October 1, 2012. To arrive at this date, I simply fit a straight line to the more or less linear decline in search volume for the trend since its outlier peak in 2007. And by "fit" I mean "drew in Photoshop."
"You can see below that extending the trend out to infinity sees it cross the x-axis almost exactly three-quarters of the way through 2012. That's the point at which the term "Web 2.0" will have become so tired and worn out that even the PR professionals who refuse to drop it will finally get a clue.
"Of course, "Web 2.0" might not really die. Like other terms with historical significance, its search volume could asymptotically approach zero...." (((
