I just suggest you will try to add logo header and add some color and graphic images in your site layout...
i would make leeter spacing a little wider in FF3 it looks a little crowded, also line-height in related posts need some more px, actually looks like you have line-height for all body 15px, i would give it some more
Did you have to do caps? if your using word press is the pink theme a joke? when I think educational and informative I think green and gray.
