What Can A Website Be Used For?

I’ve seen all sorts of websites for almost everything on this world wide web, and some of these websites are absolutely ridiculous and others are really fun, i spent some time on neal.fun or neal.universe or whatever it is, and then you know, there’s all sorts of other content on here. I don’t really know what to use the internet for, or how to add value to this. I’m trying to learn how to use wordpress, but it’s all very slow since there’s a massive backlog of comments on here. What do I do?
Best,
