I love the simply stated yet perfectly executed design of the Lullabot website. The rhythm of this site is superb as you scroll down the page. Everything just queues up perfectly for you. The site starts off as a place to get into what type of work the firm does, then evolves into an information hub as you get down the page for smaller bits of stuff. Very well done website.
I also very much love it when the people behind a new site design write about what they were thinking when they pulled it off. Like in this post from Jeff Robbins on the Lullabot redesign.
