People didn't know about that site? o_O I used that a long time ago for my GTO. And yeah, they hate NarutoFan.com because they charge for some manga, IIRC, and they wanted to stop Tazmo (hurr durr) from doing that by providing the exact same stuff for free on their site.
History lesson aside, OneManga is still a great source. It may not have an online reader anymore, but you can still track your manga, and they almost always have links to the original source of the manga. Unless it's SleepyFans because nobody knows where the hell they reside.
