From my experience on this, the single biggest determining factor on one's opinion is whether you have kids (I have elementary-age kids). We have to work like mad to limit screens, but it is an uphill battle. Their schools use them, th

Yup, it can get hot in the summer. On the flip side, winters are great! The best time of year is Mar/Apr and Oct/Nov. Absolutely gorgeous. There's a reason why SXSW and ACL are scheduled at those times...

I lived in Shenzhen from 2007-2011 and can confirm that large amounts of recyclables were shipped to China. Open-air facilities hired pickers to go through the material and pull out whatever they could before disposing of the remainder (by

I have all the respect in the world for what Mr. Musk has accomplished, but it has come at an amazing cost to the people around him. He is worshiped from afar but reviled by many the closer you get to his inner circle. Go read "Elon Mu
