My son (23 months) loves the "big kid" playgrounds. He is a cautious child, and he definitely follows the progressive learning model in how high he climbs. However, he is adopted, and we have to worry about social workers disapproving of how we raise him, and we could get in big trouble if he got hurt, so I am one of those mothers who tends to hover around her child on the playground. It's not because I am overprotective, but because society has gotten to the point that the state will take away your child if he cuts his finger, practically. In a civilization's progress, I think sometimes we start to go overboard, and that's when society becomes corrupt and a new, younger society takes over. Look at the cycle of civilization. Ancient powerhouses are no longer around. We don't just get more civilized, we go back and forth.

Any good techie wants to try the next big thing, even if the craze doesn't last that long. However, getting celebrities to post content that vast hoards of people are interested in seeing is more what Google is going after here. It gets people to actually use the product and maybe tell their friends about it-- the same people who tell their friends they are going to go to a concert.
