Hi Toni, glad to hear my thinking on this subject resonated. The effect of internet use on the mind is a rapidly growing field. Some books you might consider:

Present Shock by Douglas Rushkoff
The Distraction Addiction by Alex Soojung-Kim Pang
Digital Vertigo and The Internet is Not the Answer by Andrew Keen
TechGnosis by Erik Davis
The Shallows by Nicholas Carr
Free Culture by Lawrence Lessig
Technopoly by Neil Postman

These books look at the internet and interiority — individual and collective (cultural) and it is fascinating stuff. Good luck with your writing. Nice to hear from you.
