I won't, but mainly because I think Zuckerberg has it backwards. I don't want my phone to be focused on the other people in my life. My phone is very personal. There are far more things I do on my GS3 that DON'T involve sharing, or seeing what others are doing. This includes gaming, reading, listening, shopping, and most importantly assisting my life. So it's zero steps to the news feed, but how many extra steps to get to Maps, or the traffic for my ride home? How many extra steps to get to my calendar, which I use as a widget right now? It's not my friends' phone. It's mine.
