In what browsers on what OSes installed on what particular hardware? You 
have no control over the hardware a visitor is using to view your site. 
I could be running a 19" monitor at 640x480 resolution because that's 
what I need in order to see things. Or I could be like a friend of mine 
who ran his 17" monitor at 2048x1536 resolution. (I even once ran a 15" 
monitor at 1600x1200.)

That's the important thing, and easiest if you start with the assumption 
that the visitor already has their preferred font size set.

I think that the most likely browser settings you'll encounter in 
general public use are the browser's stock, default settings. So keep a 
test system around with your chosen browsers installed with their 
unchanged installation defaults ...

You're still trying to prescribe the visitor's font sizes. You have no 
control over it, so why spend any time bothering with it?

And who says that CNN or any other particular site is doing it "right"? 
Way too many sites are designed by Graphic Designers Who Must Look Kewl 
At Any Cost - and media companies are some of the worst offenders in 
that area. (An aside: some of the most Absolutely Totally Kewl - and 
completely unusable - sites I've seen have been the home sites of web 
design firms ... )

I don't adjust my font sizes so that any particular site's font looks my 
chosen size. I set my chosen size, and kick the font size up or down if 
needed by some particular site. I have almost never encountered a web 
site where I had to kick the font size DOWN.
