I just finished reading all of Bakuman on onemanga.com:

It's interesting in that it's a manga about writing manga! Honestly written, and a wonderfully self-reflexive look inside the hidden world of manga-making. It follows the adventures of Moritaka "Saiko" Mashiro and Akito "Shujin" Takagi who start upon their road to manga excellence in high school, and face the ups and downs of the publishing world.
