Of course not, but i just took a theme by default. If you don't like it, we can surely improve it in some ways

For my personal tastes, i think i should increase the contrast at least, to make for exemple white fonts on the posts, and change a few other backgrounds (the white bg for sticky posts is ugly imo).
In last resort, having another theme instead / in addition of this one is possible too of course.
It is not the most important, yet it's not nice if one always feel the look is crap when coming somewhere...
