Font Tester is a free online font comparison tool. The tool allows you to preview and compare different fonts side by side with various CSS font styles applied to them. According to the site it is very useful for web developers who are looking for just the right font/style/color to use in their pages. I’ve stumbled across this site a while ago and I’ve been using it since. I found it very useful when I want to know what the content will look like with different styles done to it.
