I saved a personal, private backup of everything I've posted -- 3,794 posts, not including this one -- and then deleted it all except the first post.
First, the why: the internet never forgets, but that's not how people work. "I like to remember things my own way. How I remembered them, not necessarily the way they happened." The person who posted entries here ten years ago is a different person than me, and I see no reason for that older person to stay around*.
I will keep this account to keep up with the people who are still around on here. I wish you well and hope that we keep in touch; come to San Francisco sometime, join me for dinner, crash on my couch, but don't expect another post from me. I hope to put up future new stuff on my website, so either check back there or subscribe to the feed.
* I won't pretend the content I've posted isn't available through other places, but I can at least make it inconvenient/harder to find.
