Manga! Manga!
I know it’s probably due to publishers, but I really hope we have more manga to choose from for Kindle in the near future. The current selection is mostly yaoi (which I don’t mind) and crap (which I do). I would gladly re-buy many of my manga for Kindle, given the chance, and I’m sure I’m not alone in this. It would certainly be a godsend for keeping up with long series when I’m travelling.
