It is important that text be clear and easily read, which is why most 'content' is done using a very simple font. The fonts for paragraphs are also limited to the font styles that are common on all computers. Why? So everyone can read what you have to say, of course!

Is there no place for all those cool fonts you have on your computer?

YES, by creating a graphic, but remember you still need to be sure it can be read. Titles are a good place for decorative text. The styles and effects are useful here too, so be sure to check out that section of the site.
