Nice site with good info and theme. Only thing I may possibly suggest is that you change the main post font, as it's slightly difficult to read (possibly due to the font itself), and for users without the font on their computer, they'll likely just see Times New Roman.
Safe fonts (those that
all users will definitely be able to see are as follows:
arial, arial black, comic sans ms, courier, courier new, georgia,
helvetica, impact, palatino, times new roman, trebuchet ms, verdana
Hope this helps, and well done again for a well designed and informative site
