Usability 
Web Developer Jeremy Keith's Adactio, is a web design and development blog and a showcase of Jeremy's work.
Adactio was cited recently in James Pearce's post "Not a mobile web, merely a 320px-wide one" as an example of the new school of "Responsive Web Design" which advocates using a fluid design and CSS media queries to create sites that adapt to a variety of viewport widths including those of mobile browsers. Pearce argues that making a page fit the screen's width without considering document size and the different use cases of the mobile context tends not to give an optimal mobile user experience.
I agree with James but I noticed that, unlike his other examples of "Responsive" sites whose pages average hundreds or even thousands of kilobytes in size, Adactio's pages, with the exception it's image heavy portfolio page, are quite svelte with the three I checked ranging in uncompressed size from 23 for the front page to 69 KB for a lengthy post.
