I love the look of Todd Dominey’s What Do I Know. Todd is a web designer and by all indications a very good one. On top of the great look I also envy the technology. Todd has built the site using XHTML and table-less CSS. These are things that I am just beginning to learn about but the ideas appeal to me greatly: well structured content (XHTML) separated from presentation (CSS).
Other great looking weblogs: Textism, dollarshort.org and Sew Wrong (the last two by Mena Trott, co-creator of Movable Type).
