Pro tip: nobody seems to remember that guestbooks were half the fun of old sites, and I have got proof in a shoebox
I have been digging through a shoebox of printouts from 1998 and 1999 because I finally got around to scanning them, and I counted 62 guestbook pages from sites I visited. Everyone talks about the flashing GIFs and the hit counters when they talk about 90s web design, but the guestbook was the real draw. You would sign one, then go back a day later hoping the webmaster replied, and sometimes a total stranger from Ohio or Wales would leave a note under yours. It was slow and clumsy, sure, but you actually read every entry on the page because there were only 15 of them, not 15,000 comments sorting themselves by likes. I know this because I still have the printouts, and my own site's guestbook filled up with 84 entries in about 7 months before I shut it down in 2001. The thing people get wrong is acting like guestbooks were just a chore you stuck on your page, when for a lot of us they were the whole community. Does anyone else still have old guestbook printouts or screenshots stashed somewhere, or am I the only one who kept paper copies of that stuff?
