When your designing your site do you think about logo dominance, what I mean is does your logo stand out more than your content or do you have your content stand out more?
I prefer my logos to be simple and minimal. I always just have the sites name in one line (about 35-30px in height) and have it aligned in the centre. I've seen some sites that have logos that are at least 500-600px in height and to be honest, they may look really good, but then it's the constant effort of having to keep scrolling down (even on a high res) to get the content fully on screen.
