Blogger.com homepage, nice UI
I find Blogger.com an asthetically pleasing site, and the best of the blogging service providers. There is a lot of information without being cluttered. Awesome use of images and color.
If I were to change something I would increase the presence of the search box, and decrease the presence of the explore blogs. This is one of the most common problems of pages trying to get me to explore other content or have me search for an answer before asking a question.
