For a long time, I was looking for a layout that was made use of the full width of the screen. Today I found the 'Incipient Template', which actually has a kind of responsive design.
I didn't customize it (yet...), for now I like it. It's clean, fast and nice to use (thanks to Amanda from bloggerbuster.com). Oh yes, I just added the syntax highlighter on it, to show the code samples on a nice way. So I hope you'll enjoy the new layout. However, it's all about the content ;)
