Thanks so much for your post, Bart. I'm grateful to have received this sad news from you in my feed reader instead of just a slew of retweets. It was a gentle shock. I knew his health wasn't good but I was so hopeful he'd been improving. I'm so sad. It's confusing grieving the loss of someone I've never met in person, but I feel he gave so much and he will be terribly missed indeed. Long live his legacy and inspiration!
