Fun for geeks

A friend of mine told me about this website, http://www.w3schools.com, for learning HTML coding. I'm having a lot of fun! I already had a basic knowledge of HTML, and now I'm learning XHTML, CSS, and Javascript! Hence the title, "Fun for geeks". Seriously, though, CSS is awesome. I don't know why they didn't think of it 10 years ago, since the principle of it is used in so many other things, like networking. That's pretty much all I have to say. I'm a geek!
