Small and colleagues monitored the brains of 24 adults as they performed a simulated Web search, and again as they read a page of text. During the Web search, those who reported using the Internet regularly in their everyday lives showed twice as much signaling in brain regions responsible for decision-making and complex reasoning, compared with those who had limited Internet exposure. The findings, to be published in the American Journal of Geriatric Psychiatry, suggest that Internet use enhances the brain's capacity to be stimulated, and that Internet reading activates more brain regions than printed words. The research adds to previous studies that have shown that the tech-savvy among us possess greater working memory (meaning they can store and retrieve more bits of information in the short term), are more adept at perceptual learning (that is, adjusting their perception of the world in response to changing information), and have better motor skills.

Its not a sign of evolution, but more a ditinct reation to training the brain to quickly scan material. Much like someone who can speed read. I don't see how the capacity and usage of the capacity trigger changes at the genetic level to be passed on. This is just sillyness.
What causes evolution is selective genetic traits being propogated over generations. Its a nice social psychology study, but provides no evidence to support its claims of evolution. It may prove that the brain is already powerful enough to reconfigure based on patterned usage. It is most definately not evolution.
