I've been building web sites since mid 1996, and little web-based dev tools have come and gone. This site is one of the most well implemented and well conceived tools with a specific focus that I have ever come across. Check it out!

About Typetester: "The Typetester is an online application for comparison of the fonts for the screen. Its primary role is to make web designer's life easier."

I couldnt agree more. The best unsung feature of this site is that a developer can let their client loose on it, let them experiment to their heart's content and once they have arrived at their ideal stylesheet, they can copy and paste the CSS style into an email and send it to you. Snap!
