On some web pages I visit the font size is so large, it is almost impossible to read the headlines. Some pages are normal. I have seen on a few pages that you can change the font size for that particular page, but the ones that I am having trouble with do not offer that option ( at least that I can see).
Here's an example: my wife's yahoo page is larger than normal, CNN.com is normal, Slacker radio is normal, one of the pages about my favorite football team is large. So the issue is kind of hit and miss.
