I’m pouring one out for JManga. Today, May 30, 2013 is the last day of the service before its complete shutdown. Can’t really say why exactly it failed. I’ve read elsewhere that even its most popular titles only sold in the hundreds of copies. And I’ve read speculation that the marketing was not as good as it could be, or that there were just too many pirate manga sites to complete with.
In any case, I was a paying customer who will miss them. Thank you JManga.
