Typetester: A Great Tool for Comparing Fonts

I just finished a conference call with a website designer and found out about a great comparative tool called Typetester.

What is Typetester?

The Typetester is an online application for side-by-side comparison of fonts for the screen. You can select three fonts at a time for comparison (in standard, bold, italics, all caps, etc.)

I believe Typetester can be a valuable time-saver, especially if you do a lot of web-based publishing or design.
