It started with Flickr. I had this blog, see, for years and years starting in the late 1990s, and people didn’t even call it a blog, and they’d say, I read on your Web site that you bought a bike. Or, I got your email newsletter and I can’t believe you tried to save Brad Pitt from being kidnapped. Or, I’m sorry to hear about your parents; I can’t believe you wrote that on your Weblog.
