Why it's best NOT to choose your own fonts
With a few exceptions, you should use the fonts built into the anaZana template (this also applies to the blank template). This is because there are certain fonts that are universally read the same way on various browsers.
If you choose your own fonts, you run the risk of odd effects in different browsers: your site will not look professional.
If you do use specialized fonts, do so only on a limited basis, within a confined area of your site. Still, this is risky.
