If you're a Win XP user and you have ever looked at web pages on your monitor and wondered, "Am I going blind or do those fonts look fuzzy?" this post from Lori Ayre on Mentat  may be helpful:
Follow these steps to amazingly clearer fonts everywhere including websites and even on Word documents:
1. Go to Control Panel
2. Select Display
3. Choose the Appearance tab
4. Click on Effects
5. Where it says "Choose following method to smooth edges of screen fonts", change Standard to Clear Type.
