I like Photojojo and their simple, but effective interface designs. Photojojo begun as a newsletter and grew also as an amazing online store. Now they have their own book.
I like the single promo page for their book, sweet and simple. Maybe the text about the book can be revised to make it more simple and interesting to read as being more descriptive of the book (some snapshots of the book pages may also help), but overall it is very good. The live Twitter feed adds to the hype.
