Aries hit it on the head. We don't see kids playing in their yards anymore. They're all inside on their XBoxes, or whatever the rage is. When you do see kids, they've got their phones out. For me, it has enhanced my life. When a small boy on the farm, we had a rotary dial phone. It got used for purpose-filled calls. Dad calling the John Deere dealer to see if they had a part he needed to repair one of the farm implements would be an example.
When I graduated high school, most of my classmates went off to college and never returned, and I lost track of them. Come Facebook, I found most of my graduating class. I have found long lost cousins as well. Going online, I can search out information when making repairs to my vehicles, or search out products. I have found items online at sites such as Amazon and McMaster Carr (industrial and automotive) that aren't available locally.
