Guestbooks

What it was

A public guestbook let visitors leave short messages on personal homepages. It turned lonely websites into small social rooms.

Why people remember it

• People signed with handles, hometowns, and tiny inside jokes.
• Spam eventually found them, but the format made early websites feel inhabited.
• A guestbook was proof that someone had really been there.

What replaced it

Usually a platform feature, a private analytics dashboard, a cleaner app pattern, or a feed. The behavior rarely disappears; it gets renamed and absorbed.
