1) Gray and white doesn't always make a bad site - cute rhyme, but clever message - sometimes it's fine to use white and shades of gray in a simple, clean site. You have used this colour scheme very effectively by having a very very light shade of grey (Or maybe it's actually white) as the background behind text, making it easy to read and pleasant on the eyes. Using a slightly darker shade of grey for the right sidebar was a wise choice too.
2) I love the smooth, swish and slick navigation bars, how they all fade in and out like that - but perhaps consider changing the colour of the menu items to a pastel shade of blue or green, just to add a little bit of colour?
3) For internet users in countries that have a download limit, like me
, I think your site should be set to only display 7 posts on the homepage.
Overall a great effort and a simple, yet clean and pleasant website.
