Everyone had a blog. I didn’t. But then, after a while, I understood what a blog is for: it’s not about publishing to random strangers, it’s about having stable, linkable locations for non-ephemeral thoughts, so you can point people to them, and so they can leave comments.
My home page is http://www.red-bean.com/kfogel/.
