Consider to switch to a sans-serif typeface in the Wicket guide

I know this is a matter of opinion, but I think you should really consider to change typeface used in the Wicket guide to a sans-serif variation.

It looks cleaner and better. But most important - it's definitely more readable on the Web.

Verdana, Google's Open Sans or Roboto...these are very nice modern fonts.

Examples of very professional pages using a sans-serif typeface:
