"Why do it?" is a fair question when it comes to essentially giving away some kind of effort. But I can say two things to answer it. One boring and pedantic and nerdy, and one...less so.
First, boring/nerdy: much of the Internet is archived. It's not nearly as ephemeral as it was when we were teenagers.
Second: the reason to do it is that you, or someone else, gets joy out of it. Maybe you really like writing reviews. Or people love reading them. If that happens, then it almost doesn't matter how long it stays up. If you post something funny, and you make people laugh and feel a little better...isn't that a good reason to do it, even if all of it vanishes a minute later? They still laughed. They still felt better. You still did that.
Anyway, that's how I try to look at all this stuff. If the site closed tomorrow, yeah, I'd be sad. I'd be sad if all this stuff was gone. But I still know a lot of people would have gotten a lot out of it, and that will always be true, whether there's a record of it or not.
