You never know. Butterfly effect and all that. It adds up. Best example I know of is when I was younger and playing WoW, my brother was explaining gemming your gear to me. I told him "what will a +4 intelligence gem do really?" But you add up all the gems on all the sockets on the gear and it makes a huge difference. The difference being the difference between a strong character and a weak one and living or dying. Each you in google is a potential gem in the system. Or you can be an empty socket. Add all those up and it does have a huge effect on the outcome of Google (and the stock price).

I apply this theory to many diverse subjects- voting, finances, human health and car maintenance (once one system is suboptimal or impaired, others often follow). Keep your sockets gemmed. :)
