The Brain and the Internet

There have been a few news and magazine articles recently about how the internet may be changing how we think, affecting our focus, even re-wiring our brains.  I got wondering about this, and an older article about Asperger's syndrome and the Autism spectrum, and it ended up as a longer essay.  Below is an excerpt, the rest of it is here, in the Thoughts section of the site.

Bill Thompson's article for BBC News, Changing the way we think, referenced an article by Nick Carr in Atlantic Monthly, Is Google making us stupid?  Carr says he has lost some of his deep focus ability and wonders if the internet is to blame, definitely an article worth reading.  Another BBC News article Is computer use changing children? includes quotes from neuroscientist Baroness Greenfield, who wonders if the rise of attention deficit disorder diagnoses is related to how children are exposed to instant access media through the internet.

I'd like to know what you think of it.  Has your brain been re-wired lately?
