Blogger is pretty awful when it comes to customizing or controlling much of anything.
This said, I'll probably move over to Tumblr or make a Wordpress blog, so I guess keep your eyes peeled for that.
And welcome. Throughout the life cycle of this blog we will cover not only advertising and design trends, but maybe even a few how-too's, not to mention looking at a few different companies current strategies and how they could be improved, or why they're currently so effective.
