Guestbook — sign the wall

What is this? A guestbook — the thing websites had before feeds. One wall, every visitor who cared enough to sign it.

How to sign: sign in with just your email (magic link, no password), write your note in the box on the right, hit post. Done — you're on the wall.

Why it matters: analytics tell me numbers; the wall tells me humans were here. I read every entry, reply to most, and on rough days this page does more than coffee.
