I also had some Marvel Superhero 'Computer Fun' books, but couldn't find a link to them anywhere.
My wife uses Facebook Religiously - does that count?
Seriously though - I've got no Facebook, LinkedIn, Twitter etc. and I've managed just fine.
No way would this work in our house, kids are 6 and 22 months.
I've already found items waiting for me in my Amazon cart after my daughter has played with apps like the Easy Bake Oven - which is a cute app, but includes links to add related supplies to your shopping cart...
