Dunno if any of you actually READ the Twilight mango, but what I read, the dude who made the narrative transition actually tried to make an effort so it wouldn't go to complete [parasitic bomb]. The art is Deviantart-grade stuff, but the script itself isn't amazingly bad. It's just Twilight, but they made a decent transition. You also get to see how ridiculous the whole thing is, since it's based of the book rather than the movie. So, yeah. Mary-Sue Bella at her whole potencial, and Eddy with a skin that glows like Las Vegas at night. All in all, it was a fairly entertaining half an hour. (and I'm sad to say, but still better than quite alot of the comics/manga I sometimes find).
But yeah. There's not enough demand for unpopular manga around here for it to be profiteable. A store only orders a few copies of whatever [parasitic bomb] we're into, if they can be sure that [parasitic bomb]'s gonna sell. And your corner store in the middle of the town you live is not gonna have it waiting for YOU.
A good solution would be a net subscription. Problem is, what would you pay, and would you pay for more, or less manga every week? Not everyone likes every manga the japanese magazines offer. And the service being currently used for comics is still very much an experiment, to see if the audience accepts it. Manga authors don't want to go through all that [parasitic bomb] just to provide to the small number of people who read this or that manga, so they just sue so they don't get their material outside.
What I don't understand, is the need for companies to sue over small-time manga that few people read and which is never gonna get published here, like Otaku no Musume-San, which was taken off OneManga awhile ago due to copyright enfringement. It's a kind of manga very much in tune with japanese culture, and really not something that'd sell. WHY sue over that, and not over Naruto, Bleach or One Piece?
It's just kinda stupid.
