Small comment: you are using faux bolds on your headers (Bestsellers, Recent in Fiction, Recent in non-Fiction in dark gray along the top.) This is hurting readability, especially since the font is already bold. Essentially, you are applying a low-quality bold (generated by the browser or text rendering layer) to the high-quality bold that was designed by the typographer. This isn't just font wankery, it makes it hard to read the headings.

The easiest way to fix this is remove the bold declaration from your CSS. The text will still be bold, because you are using a bold font.

The other way to fix it is to go into your @font-face declarations for droid sans bold, and change the declared font-weight to be bold. This tells the browser that the font is already bold, and not to make it more bold.

Here's a before and after in FF (latest) on OS X. Faux bold: http://cl.ly/image/3R0B0z1s0A3g. Real bold: http://cl.ly/image/2A1N3w083h47.

I've given up and started modifying sites directly via the Stylish plugin, if I must use them, or simply ditching them, if I needn't.

Thanks for the comment. The bold is applied again in the css...not ideal. Removing it makes it less heading like though. Can increase the font but not sure if it will suffice.
