So is it like a webring but random?

I would start with some HTML tutorial on the internet and host that on nekoweb or neocities. That way you can concentrate on learing to create a website and deal with the hosting stuff later. May people offer free templates, too. Just surf around on the websites there and see what other people make :) And yes, linux is way better than windows in every way. If you mostly use stuff like your browser or steam, it is not hard to switch, either.
