The best example, of late? One of my favorite blogs, Indexed, has been offered a book deal, with Penguin's Viking Studio. For about seven months, Jessica Hagy has been doodling absurd little diagrams that explore and explain the relationships between all sorts of things, like the correlation between money and nihilistic fashion trends, or the futility of New years resolutions. In a surprisingly insightful manner, these doodles on index cards poke fun at fashion, politics, television and every other area of culture and human nature.
This site is a hoot, and I'm looking forward to the book.
