I'm very interested in learning about this need! I would love to know where or how I can engage with manga artists so I can learn more about where they're publishing currently, what's not working, how they would like publishing to work, etc. (I am a web developer.)
I have read manga throughout my life and have long thought that the current manga infrastructure is unjustifiably broken. (I am only familiar with Japanese manga, however.) At least for Japanese manga, the publishers in Japan make their manga so incredibly inaccessible to foreign readers despite the huge popularity in some of their works and the unbelievable amount of scanlation work that fans put into (voluntarily!).
As an avid manga reader, I would love to see a platform where I pay a monthly fee to legally read manga and support creators. But I am not a manga artist and don't understand their needs and obstacles, so I would love to learn more.
