All pages in Google Chrome are rendered with a very thin, bad looking serif font
Before you go blocking fonts and so on, first check this page:
http://www.google.com/webfonts

How you get rendered the fonts? On my chrome - without any problems, the chrome CAN render different fonts.

You can try these commands from the Terminal.app

sudo atsutil databases -remove
sudo atsutil server -shutdown
sudo atsutil server -ping


the above will remove your font cache. Work only in snow leopard!
