Much to do about Web 2.0 ... where is Web 3.0?

There is much-to-do about Web 2.0. It is cloudy in New Jersey this morning; perhaps that is clouding my small brain in this regard.

What is Web 2.o? It was promoted by Tom O'Reilly in 2004. Web 2.0 supposedly is the catalyst, the tremor that kicked-off an important shift in the way digital information is created, shared, stored, distributed, and manipulated.

Here is my issue. Amazon.com in the mid to late nineties was the leading, bleeding edge of the Web (even with or without their purchase of Junglee and others) - dynamic authoring of customer feedback on its website, showcasing related purchases, etc; they were the forerunners of what we see today. Yes today the advances in design and UI, programming techniques have propelled us forward; with Salesforce.com, Google and others we have seen a new class of apps surfacing, and more and more on-demand software concept materializing.

There have been numerous advances, which is to be expected; the underpinnings of the Web programming techniques has not changed; the concept of client-side programming and server-side programming remain, and must remain. Yes we have AJAX, PHP, Rails, etc.

Essentially my point is that this whole thing about Web 2.0 has taken on more of a marketing buzz then anything else. I cannot look back and say, aahhh yes Web 2.0 started on this day with this technical advance. There is no general consensus on what constitutes Web 2.0 nor can one clearly articulate what Web 3.0 is or will be.

Hopefully when the clouds lift so will this air of palpable gloom that hangs over me; I am ready, ever ready, to ride the crest of Web 3.0 ... please tell me there is going to be Web 3.0 and that it's coming, and that it is just around the corner; do not want to miss this one.
