The only thing I really know about manga is that there's lots of it. But now there's a fair bit less of it online, at least that's available for, erm, 'free', in less than legal terms, on bato.to. But this and many related sites, such as xbato.com, are now dead, thanks to a Chinese criminal investigation aided by the Japanese Content Overseas Distribution Organisation (CODA) (via NHK).
Bato was apparently the world's largest manga piracy website that hosted thousands of comics illegally, translating them and distributing them without permission from the rights holders.
