When I could be bothered writing this, this was an easy to install, easy to use, easy to administer LAMP-stack–based guestbook that features Akismet anti-spam protection and an overall great user experience.

It is now old and decrepit, and has bugs I can't be bothered fixing. Please do not use this, and if you do, please fix the bugs in them and send the fixes to me so I can update this shaggy old code.
