It occurs to me that there are probably thousands of other design/designer's blogs out there in the blog universe. (I know, its an amazing moment of clarity) Permit me, if you will, to point out a few of my favorite.
design*sponge - Check out the mini-trends page. A daily website run by Brooklyn-based writer, Grace Bonney.
Design Observer - A blog that focuses on design and culture. Often points out the flaws in design and designer's work.
Feed Me Cool Shit - I find the title annoying, but the information spectacular. Great design, great content on design and culture.
