People have been asking for more control over the appearance of the ads on their sites. Adsense team has now announced on their blog that their publishers can change the font face of the text in ad units on pages in Latin-character languages.
Not a bad move. But they need to add more fonts. This will make us free to use any font we need for the site content (i.e. we will not have to use verdana or arial for our content anymore).
