Questo articolo di Jeffrey Zeldman, pubblicato nel 2006, critica il Web 2.0 e le tecnologie ad esso associate (in particolare AJAX). In un certo senso, l'autore suggerisce che i limiti del Web 2.0 riproporrà una bolla simile alla precedente. Il suo articolo si conclude in modo piuttosto deprimente:

It’s only castles burning

To you who are toiling over an AJAX- and Ruby-powered social software product, good luck, God bless, and have fun. Remember that 20 other people are working on the same idea. So keep it simple, and ship it before they do, and maintain your sense of humor whether you get rich or go broke. Especially if you get rich. Nothing is more unsightly than a solemn multi-millionaire.

To you who feel like failures because you spent last year honing your web skills and serving clients, or running a business, or perhaps publishing content, you are special and lovely, so hold that pretty head high, and never let them see the tears.

La soluzione? per Zeldman non rimane che passare direttamente al Web 3.0.
