If you have any interest at all in original English-language manga (or OEL manga) and how to become an American manga-ka, you should definitely be reading the current series of posts by Deb Aoki at About.com Manga, starting with Making A Living In Manga: Part 1.
As usual, Deb Aoki examines the issue with lots of delightful insight and intelligence. In her first post, she gives a list of reasons as to why the American manga-making economy is broken, including the fact that many American readers see OEL manga as 'fake' manga, thus ignore it. Which is a shame, because there's a lot of quality OEL manga titles out there! Like Dramacon and Teahouse and The Dreaming and Off*Beat and so many more!
(Speaking of Off*Beat, I can't wait for volume three to come out! It would be great if someone reprinted the first two books but I ain't holding my breath.)
