Yes indeed grame_p, you are correct. I guess it's a sacrifice on someone's part.
Either you continue making money through say, adsense, and your blog's usability is low.
Or you build your brand and have great usability/navigation, but you cut your ad earnings by who knows how much. At least until you get sustainable traffic enough to invite companies to advertise privately on your blog.
