In my former life -- okay, one of my former lives -- I wrote a book about plumbing, and the subject still intrigues me. So imagine my delight: A World Toilet Summit. In New Delhi, no less. (God, I'd love to know the number of flush toilets per capita in that city!). My virtual pal Dave Praeger is there, no surprise, and, even less surprising, is blogging about the event. All kidding aside, it's a serious subject and I love that someone besides me thinks so.
