Everyone love to read but not everyone like to read novels without any typography arrangement. And I can see a lot of space for you to improve. If you're having difficulties modifyiing ur theme so use a more user friendly blogging site. Erm when i first start blogging, i head straight to blogspot, coz i believe it's easier.

The problem for you to fix now is, tweak ur font to a smaller one, not too small but still readable and change the color of your blog or the font to enhance readability. Utilise the space on the left and right side. Or just expand the box to make ur visitor felt more comfortable to read.
