So just before Twitter was brought to its knees a few minutes ago, my whole stream was full of mourning for a successful business leader who made some really cool products and died today. I thought this was maybe a little much, so I went looking for a list of people who’ve died this year to provide some perspective, and found out that Wangari Maathai died last week, which doubly brought home the point I was trying to make in that I hadn’t heard about it until just now. RIP, Wangari. You did real good.
