A little darker border around the content and some more padding in the header would be nice. Overall it looks nice and clean.
I love this one, it vaguely reminds me of a newspaper (format and typography).
And I agree with the previous poster, the only thing I’d change is to extend the shading along the sides to the bottom and maybe just a bit more padding between the title, the header and the first post.
Otherwise it’s perfect, good job ^_^
No back ground color…. and what part does have a background color doesn’t go all the way to the bottom.
