I think he is trying to complain that Shounen Jump values popularity of series over their quality, such as how they kept a shitty manga like Bleach ongoing past its prime, and he is using Bakuman as a reference, but he chickens out in the end.
@Almozayaf: he doesn't understand what you said not why Shounen Jump do what they do.
Was mostly what i thought after reading the series, what the guy above said said sense though, good job working it out, you could work as a translator for broken english to a more understandable english! All the top titles are popular because they are aimed for shounen even though some are just popular because they have endlessly cool and pointless battles and a weird story to accompany it after years of serialization *looks at Bleach for a example but stops saying its name in fear of raging fans* Quality is irrelevant, popularity with lesser quality and more quantity of endless battles is relevent or as i like to call it $$$.
I also don't like how they operate, but it's the most efficient way.
You can't really determine the quality of a series, since quality is usually subjective. ie, I think Sakisaka Io's works to be hackneyed [average, mindless romance] but almost everyone who reads her works think that her manga are high quality and perfect. [great emotional depictions and realistic situations] Thus, they can't rely on something as fickle as quality of a series to determine what to publish or not. [Even ratings are fickle. Compare MU's ratings to, say, MAL's; they're totally different.] Some people say that a high quality series depends on how the series depicts issues realistically and how original the story is, whereas others like myself judge a series' quality based on literary elements such as symbolism and foreshadowing. Thus, SJ looked for a way do determine what makes a best seller.
As a publisher, they need find a good series that will be popular among readers. So the only way to know what the readers like is to ask the readers themselves. They set up the ranking system as a way for readers to share their opinion on a series and whether the series should continue running or not. With this ranking, they filter out the unpopular ones and keep the lucrative, popular ones, which aren't always good to us. [After all, a company's goal is to make money.] This ranking system worked fantastically in Japan, making SJ the most popular and most read manga magazine there.
As a result of this ranking, most mangaka [excluding mangaka of the big 3] that work for SJ are prepared for the fact that their series would be cut off at any given time, so they try to cram as much information as possible into each chapter and make plot arcs as short as possible. These manga literally run on with no plot because if they were to incorporate a functioning plot, it would be difficult to end if it's suddenly axed. Ex: Double Arts had a legit plot, but it was axed half way and Komi Naoshi was forced to end it in an illogical way. Manga is an art form; art takes time to develop.
I personally don't like this way of functioning, since it prevents a manga from developing into its full potential. I'm pretty sure the mangaka you listed thought the same way. The worst thing that a mangaka can experience is their work being cut off and made fun of before they could develop it to its full potential. Like judging a book by its cover. But, it works so I can't really complain to them...
