Why are "personal homepages" listed as dead? Sure, they're not as ubiquitous as they used to be, but almost every tech-adjacent person I know has one. Webrings and guestbooks are also very much still a thing. I'd say they are far from dead.
They used to be part of your ISP. You got a usenet server, and a mail server and a web server with a certain amount of space, just as part of signing up. This meant that everyone had one, you didn't have to go sign up somewhere else. You still could if you wanted to have a URL that didn't have your ISP's name in it.
And few people used the ISP mailbox because you couldn't take it with you when you left. Hell, I got my gmail during the invite only era
